  • Status of the chiral magnetic effect and collisions of isobars
    • Authors: Volker Koch; Soeren Schlichting, Vladimir Skokov, Paul Sorensen, Jim Thomas, Sergei Voloshin, Gang Wang Ho-Ung Yee
      First page: 072001
      Abstract: In this review, we examine the current theoretical and experimental status of the chiral magnetic effect. We discuss possible future strategies for resolving uncertainties in interpretation including recommendations for theoretical work, recommendations for measurements based on data collected in the past five years, and recommendations for beam use in the coming years of RHIC. We specifically investigate the case for colliding nuclear isobars (nuclei with the same mass but different charge) and find the case compelling. We recommend that a program of nuclear isobar collisions to isolate the chiral magnetic effect from background sources be placed as a high priority item in the strategy for completing the RHIC mission.

  • Excited state mass spectra, decay properties and Regge trajectories of
           charm and charm-strange mesons
    • Authors: Virendrasinh Kher; Nayneshkumar Devlani Ajay Kumar Rai
      First page: 073101
      Abstract: The framework of a phenomenological quark-antiquark potential (Coulomb plus linear confinement) model with a Gaussian wave function is used for detailed study of masses of the ground, orbitally and radially excited states of heavy-light Qq̅, (Q=c,q=u/d,s) mesons. We incorporate a ##IMG## [] correction to the potential energy term and relativistic corrections to the kinetic energy term of the Hamiltonian. The spin-hyperfine, spin-orbit and tensor interactions incorporating the effect of mixing are employed to obtain the pseudoscalar, vector, radially and orbitally excited state meson masses. The Regge trajectories in the ( J , M 2 ) and ( n r , M 2 ) planes for heavy-light mesons are investigated with their corresponding parameters. Leptonic and radiative leptonic decay widths and corresponding branching ratios are computed. The mixing p...

  • Dynamical mass generation in QED 3 beyond the instantaneous approximation
    • Authors: Hai-Xiao Xiao; Jian-Feng Li, Wei Wei, Pei-Lin Yin Hong-Shi Zong
      First page: 073102
      Abstract: In this paper, we investigate dynamical mass generation in (2+1)-dimensional quantum electrodynamics at finite temperature. Many studies are carried out within the instantaneous-exchange approximation, which ignores all but the zero-frequency component of the boson propagator and fermion self-energy function. We extend these studies by taking the retardation effects into consideration. In this paper, we get the explicit frequency n and momentum p dependence of the fermion self-energy function and identify the critical temperature for different fermion flavors in the chiral limit. Also, the phase diagram for spontaneous symmetry breaking in the theory is presented in T c - N f space. The results show that the chiral condensate is just one-tenth of the scale of previous results, and the chiral symmetry is restored at a smaller critical temperature.

  • ##IMG##
           processes in the BLMSSM
    • Authors: Xing-Xing Dong; Shu-Min Zhao, Xi-Jie Zhan, Zhong-Jun Yang, Hai-Bin Zhang Tai-Fu Feng
      First page: 073103
      Abstract: In a supersymmetric extension of the Standard Model (SM) where baryon and lepton numbers are local gauge symmetries (BLMSSM), we investigate the charged lepton flavor violating (CLFV) processes ##IMG## [] after introducing new gauginos and right-handed neutrinos. In this model, the branching ratios of ##IMG## [] are around (10 −8 –10 −10 ), which approach the present experimental upper bounds. We hope that the branching ratios for these CLFV processes can be detected in the near future.

  • Sub-leading flow modes in PbPb collisions at
           ##IMG## []
           from the HYDJET++ model
    • Authors: P. Cirkovic; D. Devetak, M. Dordevic, J. Milosevic M. Stojanovic
      First page: 074001
      Abstract: Recent LHC results on the appearance of sub-leading flow modes in PbPb collisions at 2.76 TeV, related to initial-state fluctuations, are analyzed and interpreted within the HYDJET++ model. Using the newly introduced Principal Component Analysis (PCA) method applied to two-particle azimuthal correlations extracted from the model calculations, the leading and sub-leading flow modes are studied as a function of the transverse momentum ( p T ) over a wide centrality range. The leading modes of the elliptic ##IMG## [] and triangular ##IMG## [] flow calculated with the HYDJET++ model reproduce rather well the v 2 {2} and v 3 {2} coefficients measured experimentally using the two-particle correlations. Within the p T ⩽ 3 GeV/ c ran...

  • Magnetic moments and g -factors in odd- A Ho isotopes
    • Authors: E. Tabar; H. Yakut, A. A. Kuliev, H. Quliyev G. Hocşgör
      First page: 074101
      Abstract: The ground-state magnetic moment, g K factor and quenching spin gyromagnetic ratio have been calculated using the microscopic method based on the Quasiparticle Phonon Nuclear Model (QPNM) for 155−169 Ho nuclei for the first time. It is shown that the residual spin-spin interactions are responsible for the core polarization, and because of the core polarization the spin gyromagnetic factors are quenched. By considering the core polarization effects, a satisfactory agreement is obtained for the computed ground state g K factor, which gives an intrinsic contribution to the magnetic moments. In order to assess the collective contribution to the magnetic moments, the rotational gyromagnetic factors g R have been also calculated within the cranking approximation using the single particle wave function of the axially symmetric Woods-Saxon potential. For the ground-state magnetic moments of odd-proton 155−165 Ho n...

      First page: 074102
      Abstract: Using local central Yukawa-type Malfliet-Tjon interactions reproducing the low-energy parameters and phase shifts of the nn system, and the latest updates of the nΛ and ΛΛ Nijmegen ESC08c potentials, we study the possible existence of a ##IMG## [] bound state. Our results indicate that the ##IMG## [] is unbound, being just above threshold. We discuss the role played by the 1 S 0 nn repulsive term of the Yukawa-type Malfliet-Tjon interaction.

  • A nucleon-pair and boson coexistent description of nuclei
    • Authors: Lianrong Dai; Feng Pan J. P. Draayer
      First page: 074103
      Abstract: We study a mixture of s-bosons and like-nucleon pairs with the standard pairing interaction outside an inert core. Competition between the nucleon-pairs and s-bosons is investigated in this scenario. The robustness of the BCS-BEC coexistence and crossover phenomena are examined through an analysis of pf -shell nuclei with realistic single-particle energies, in which two configurations with Pauli blocking of nucleon-pair orbits due to the formation of the s-bosons is taken into account. When the nucleon-pair orbits are considered to be independent of the s-bosons, the BCS-BEC crossover becomes smooth, with the number of the s-bosons noticeably more than that of the nucleon-pairs near the half-shell point, a feature that is demonstrated in the pf -shell for several values of the standard pairing interaction strength. As a further test of the robustness of the BCS-BEC coexistence and crossover phenomena in nuclei, results are given for ##IMG## [ht...]

  • Study of X (5568) in a unitary coupled-channel approximation of BK̄
           and B s π
    • Authors: Bao-Xi Sun; Fang-Yong Dong Jing-Long Pang
      First page: 074104
      Abstract: The potential of the B meson and the pseudoscalar meson is constructed up to the next-to-leading order Lagrangian, and then the BK̄ and B s π interaction is studied in the unitary coupled-channel approximation. A resonant state with a mass about 5568 MeV and J P =0 + is generated dynamically, which can be associated with the X (5568) state announced by the D0 Collaboration recently. The mass and the decay width of this resonant state depend on the regularization scale in the dimensional regularization scheme, or the maximum momentum in the momentum cutoff regularization scheme. The scattering amplitude of the vector B meson and the pseudoscalar meson is calculated, and an axial-vector state with a mass near 5620 MeV and J P =1 + is produced. Their partners in the charm sector are also discussed.

  • Quasiparticle structure of superheavy nuclei in α -decay chains of
           285 Fl and 291,293 Lv
    • Authors: V. G. Kartavenko; N. V. Antonenko, A. N. Bezbakh, L. A. Malov, N. Yu. Shirikova, A. V. Sushkov R. V. Jolos
      First page: 074105
      Abstract: Two mean-field potentials, Woods-Saxon and Skyrme based potentials, are used to calculate the energies of low-lying one-quasiparticle states. The spectra of the low-lying states and the α -decay spectra of nuclei belonging to the α -decay chains of 285 Fl and 291,293 Lv are calculated and compared with the available experimental data. Dependence of the splitting of the pseudospin doublets and of the energies of the unique parity neutron one-quasiparticle states on the mean field potential are discussed. As shown, the α -decay spectra could be different in the α -decay chain and at the direct production of the nucleus in a fusion reaction.

    • Authors: Jun-Hong Liu; Shu-Qing Guo, Xiao-Jun Bao Hong-Fei Zhang
      First page: 074106
      Abstract: The competition between α -decay and spontaneous fission of superheavy nuclei (SHN) is investigated by the generalized liquid drop model (GLDM) and the modified Swiatecki’s formula respectively. The theoretical decay modes are in good agreement with the experimental results. Predictions are made for as-yet unobserved superheavy nuclei. The theoretical calculations show that the nuclei 298 120, 295 119, 290 118, 291 117, 287 117, 294 116, 289 116, 286 116, 285 116, 284 115, 283 115, 283 114, 282 114, 280 113, 276 112, 275 112, 274 112, 273 111, 272 110, 265 109 may be synthesized experimentally in the near future since they not only have relatively large predicted cross sections but can also be identified via α -decay chains.

  • A comprehensive revisit of the ρ meson with improved Monte-Carlo
           based QCD sum rules
    • Authors: Qi-Nan Wang; Zhu-Feng Zhang, T. G. Steele, Hong-Ying Jin Zhuo-Ran Huang
      First page: 074107
      Abstract: We improve the Monte-Carlo based QCD sum rules by introducing the rigorous Hölder-inequality-determined sum rule window and a Breit-Wigner type parametrization for the phenomenological spectral function. In this improved sum rule analysis methodology, the sum rule analysis window can be determined without any assumptions on OPE convergence or the QCD continuum. Therefore, an unbiased prediction can be obtained for the phenomenological parameters (the hadronic mass and width etc.). We test the new approach in the ρ meson channel with re-examination and inclusion of α s corrections to dimension-4 condensates in the OPE. We obtain results highly consistent with experimental values. We also discuss the possible extension of this method to some other channels.

      Abstract: The Bethe-Salpeter equation is solved in the framework of the unitary coupled-channel approximation by using the pseudoscalar meson-baryon octet interaction. The loop function of the intermediate meson and baryon is deduced in a dimensional regularization scheme, where the relativistic kinetic effect and off-shell corrections are taken into account. Based on the experimental data at the K − p threshold, the subtraction constants in the loop function are determined. The squared amplitude is suppressed strongly and only one Λ(1405) state is generated dynamically in the strangeness S =−1 and isospin I =0 sector.

  • Neutrino emissivity of the nucleon direct URCA process for rotational
           traditional and hyperonic neutron stars

      Abstract: Based on covariant density functional theory, we study the effects of rotation on the nucleon direct URCA (N-DURCA) process for traditional and hyperonic neutron stars. The calculated results indicate that, for a fixed mass sequence of rotational traditional neutron stars, the neutrino emissivity of the star is nearly invariant with increasing frequency, while it always increases for rotational hyperonic neutron stars. Thus, rotation has different effects on the N-DURCA process for these two kinds of neutron stars.

      Abstract: The neutrino detector for the Jiangmen Underground Neutrino Observatory (JUNO) requires a large number of photomultiplier tubes (PMTs), including 15000 MCP PMTs and 5000 dynode PMTs. The TTS (transit time spread) of the PMTs is very important for vertex and track reconstruction of the neutrinos in the detector. In this paper, we study the TTS of a 20-inch dynode PMT (R12860) from Hamamatsu for different high voltage, light intensity, light spot size and different photocathode regions. The impact from Earth’s magnetic field is also studied. The results achieved in this paper will be very useful for the JUNO experiment.

      Abstract: An electron beam probe (EBP) is a detector which makes use of a low-intensity and low-energy electron beam to measure the transverse profile, bunch shape, beam neutralization and beam wake field of an intense beam with small dimensions. While it can be applied to many aspects, we limit our analysis to beam distribution reconstruction. This kind of detector is almost non-interceptive for all of the beam and does not disturb the machine environment. In this paper, we present the theoretical aspects behind this technique for beam distribution measurement and some simulation results of the detector involved. First, a method to obtain a parallel electron beam is introduced and a simulation code is developed. An EBP as a profile monitor for dense beams is then simulated using the fast scan method for various target beam profiles, including KV distribution, waterbag distribution, parabolic distribution, Gaussian distribution and halo distribution. Profile reconstruction from the deflec...

      Abstract: The Rare isotope Accelerator Of Newness (RAON) heavy-ion accelerator has been designed for the Rare Isotope Science Project (RISP) in Korea. The RAON will produce heavy-ion beams from 660-MeV-proton to 200-MeV/u-uranium with continuous wave (CW) power of 400 kW to support research in various scientific fields. Its system consists of an ECR ion source, LEBTs with 10 keV/u, CW RFQ accelerator with 81.25 MHz and 500 keV/u, a MEBT system, and a SC linac. In detail, the driver linac system consists of a Quarter Wave Resonator (QWR) section with 81.25 MHz and a Half Wave Resonator (HWR) section with 162.5 MHz, Linac-1, and a Spoke Cavity section with 325 MHz, Linac-2. These linacs have been designed to optimize the beam parameters to meet the required design goals. At the same time, a light-heavy ion accelerator with high-intensity beam, such as proton, deuteron, and helium beams, is required for experiments. In this paper, we present the design study of the high intensity RFQ for a d...

      Abstract: Laser cooling of Li-like C 3+ and O 4+ relativistic heavy ion beams is planned at the experimental Cooler Storage Ring (CSRe). Recently, a preparatory experiment to test important prerequisites for laser cooling of relativistic 12 C 3+ ion beams using a pulsed laser system has been performed at the CSRe. Unfortunately, the interaction between the ions and the pulsed laser cannot be detected. In order to study the laser cooling process and find the optimized parameters for future laser cooling experiments, a multi-particle tracking method has been developed to simulate the detailed longitudinal dynamics of laser-cooled ion beams at the CSRe. Simulations of laser cooling of the 12 C 3+ ion beams by scanning the frequency of the RF-buncher or continuous wave (CW) laser wavelength have been performed. The simulation results indicate that ion beams with a large momentum spread could be laser-cooled by the combination of only ...

  • Preliminary study of EEHG-based superradiant undulator radiation at the
           HLS-II storage ring
    • Authors: Wei-Wei Gao; He-Ting Li Lin Wang

      Abstract: We investigate storage ring-based Echo-Enabled Harmonic Generation (EEHG) superradiant undulator radiation as a possible scheme to obtain shorter wavelengths at the HLS-II (Hefei Light Source-II) storage ring. In this paper we give the designation of the storage ring based EEHG up to the 26th harmonic, where 31 nm vacuum ultraviolet light is radiated from an 800 nm seeded laser. The novelty of our design is that both the two dispersion sections of EEHG are realized by the storage ring’s own magnet structure. In particular, the whole ring is used as the first dispersion section, and two modulators of the traditional EEHG can be done with the same undulator. These two dispersion sections are realized by changing the superperiod of the present lattice structure, and more precisely by changing the focusing strengths of the present structure. Since no additional magnets and chicanes are used, the beam circulates around the storage ring repeatedly, and thus this storage ring-based EEH...
