  • A comparison of direct and indirect determinations of the masses of the
           Higgs Boson and the top quark
    • Authors: J. H. Field
      First page: 103001
      Abstract: The indirect estimation of the Higgs Boson mass from electroweak radiative corrections within the Standard Model is compared with the directly measured value obtained by the ATLAS and CMS Collaborations at the CERN LHC collider. Treating the direct measurement of m H as input, the Standard Model indirect estimation of the top-quark mass is also obtained and compared with its directly measured value. A model-independent analysis finds an indirect value of m H of ≃70 GeV, below the directly measured value of 125.7±0.4 GeV and an indirect value: m t =177.3±1.0 GeV, above the directly measured value: 173.21±0.87 GeV. A goodness-of-fit test to the Standard Model using all Z-pole observables and m W has a χ 2 probability of ≃2%. The reason why probability values about a factor of ten larger than this, and indirect estimates of m H about 30 GeV higher, have been obtained in recent...

  • QCD equation of state for heavy ion collisions
    • Authors: A-Meng Zhao; Yuan-Mei Shi, Jian-Feng Li Hong-Shi Zong
      First page: 103101
      Abstract: In this work, we calculate the equation of state (EoS) of quark gluon-plasma (QGP) using the Cornwall-Jackiw-Tomboulis (CJT) effective action. We get the quark propagator by using the rank-1 separable model within the framework of the Dyson-Schwinger equations (DSEs). The results from CJT effective action are compared with lattice QCD data. We find that, when μ is small, our results generally fit the lattice QCD data when T> T c , but show deviations at and below T c . It can be concluded that the EoS of CJT is reliable when T> T c . Then, by adopting the hydrodynamic code UVH2+1, we compare the CJT results of the multiplicity and elliptic flow ν 2 with the PHENIX data and the results from the original EoS in UVH2+1. While the CJT results of multiplicities generally match the original UVH2+1 results and fit the experimental data, the CJT results of ν 2 are slightly...

  • Pair production of the Elementary Goldstone Higgs boson at the LHC
    • Authors: Chong-Xing Yue; Lu Ma, Yu-Chen Guo Ya-Bing Zuo
      First page: 103102
      Abstract: The Elementary Goldstone Higgs (EGH) model is a perturbative extension of the standard model (SM), which identifies the EGH boson as the observed Higgs boson. In this paper, we study pair production of the EGH boson via gluon fusion at the LHC and find that the resonant contribution of the heavy scalar is very small and the SM-like triangle diagram contribution is strongly suppressed. The total production cross section mainly comes from the box diagram contribution and its value can be significantly enhanced with respect to the SM prediction.

  • Investigating the topological structure of quenched lattice QCD with
           overlap fermions using a multi-probing approximation
    • Authors: You-Hao Zou; Jian-Bo Zhang, Guang-Yi Xiong, Ying Chen, Chuan Liu, Yu-Bin Liu Jian-Ping Ma
      First page: 103104
      Abstract: The topological charge density and topological susceptibility are determined by a multi-probing approximation using overlap fermions in quenched SU (3) gauge theory. Then we investigate the topological structure of the quenched QCD vacuum, and compare it with results from the all-scale topological density. The results are consistent. Random permuted topological charge density is used to check whether these structures represent underlying ordered properties. The pseudoscalar glueball mass is extracted from the two-point correlation function of the topological charge density. We study 3 ensembles of different lattice spacing a with the same lattice volume 16 3 ×32. The results are compatible with the results of all-scale topological charge density, and the topological structures revealed by multi-probing are much closer to all-scale topological charge density than those from eigenmode expansion.

  • Possible strange hidden-charm pentaquarks from

           ##IMG## []
    • Authors: Rui Chen; Jun He Xiang Liu
      First page: 103105
      Abstract: Using the one-boson-exchange model, we investigate the ##IMG## [] , ##IMG## [] , ##IMG## [] , ##IMG## [] , ##IMG## [] , and ##IMG## [] interactions by considering the one-eta-exchange and/or one-pion-exchange contributions. We further predict the existence of hidden-charm molecular pentaquarks. Promising candidates for hidden-charm molecular pentaquarks include a ##IMG## []

  • Maximal symmetry and mass generation of Dirac fermions and gravitational
           gauge field theory in six-dimensional spacetime
    • Authors: Yue-Liang Wu
      First page: 103106
      Abstract: The relativistic Dirac equation in four-dimensional spacetime reveals a coherent relation between the dimensions of spacetime and the degrees of freedom of fermionic spinors. A massless Dirac fermion generates new symmetries corresponding to chirality spin and charge spin as well as conformal scaling transformations. With the introduction of intrinsic W-parity, a massless Dirac fermion can be treated as a Majorana-type or Weyl-type spinor in a six-dimensional spacetime that reflects the intrinsic quantum numbers of chirality spin. A generalized Dirac equation is obtained in the six-dimensional spacetime with a maximal symmetry. Based on the framework of gravitational quantum field theory proposed in Ref. [1] with the postulate of gauge invariance and coordinate independence, we arrive at a maximally symmetric gravitational gauge field theory for the massless Dirac fermion in six-dimensional spacetime. Such a theory is governed by the local spin gauge symmetry SP (1,5) and ...

  • Influence of breakup on elastic and α-production channels in the 6
           Li+ 116 Sn reaction
    • Authors: D. Patel; S. Mukherjee, N. Deshmukh, J. Lubian, Jian-Song Wang, T. Correa, B. K. Nayak, Yan-Yun Yang, Wei-Hu Ma, D. C. Biswas, Y. K. Gupta, S. Santra, E. T. Mirgule, L. S. Danu, N. L. Singh A. Saxena
      First page: 104001
      Abstract: The effects of breakup reactions on elastic and α-production channels for the 6 Li+ 116 Sn system have been investigated at energies below and near the Coulomb barrier. The angular distributions of α-particle production differential cross sections have been obtained at several projectile energies between 22 and 40 MeV. The measured breakup α-particle differential cross sections and elastic scattering angular distributions have been compared with the predictions of continuum-discretized coupled channels (CDCC) calculations. The influence of breakup coupling has also been investigated by extracting dynamic polarization potentials (DPP) from the CDCC calculations. From the predictions of CDCC calculations the relative importance of the nuclear, Coulomb, and total breakup contributions have also been investigated. The nuclear breakup couplings are observed to play an important role in comparison to the Coulomb breakup for the direct breakup mechanisms associated i...

  • Ab initio many-body perturbation theory and no-core shell model
    • Authors: B. S. Hu; Q. Wu F. R. Xu
      First page: 104101
      Abstract: In many-body perturbation theory (MBPT) we always introduce a parameter N shell to measure the maximal allowed major harmonic-oscillator (HO) shells for the single-particle basis, while the no-core shell model (NCSM) uses N max ℏ Ω HO excitation truncation above the lowest HO configuration for the many-body basis. It is worth comparing the two different methods. Starting from “bare” and Okubo-Lee-Suzuki renormalized modern nucleon-nucleon interactions, NNLO opt and JISP16, we show that MBPT within Hartree-Fock bases is in reasonable agreement with NCSM within harmonic oscillator bases for 4 He and 16 O in “close” model space. In addition, we compare the results using “bare” force with the Okubo-Lee-Suzuki renormalized force.

  • Impact of off-diagonal cross-shell interaction on 14 C
    • Authors: Cen-Xi Yuan
      First page: 104102
      Abstract: A shell-model investigation is performed to show the impact on the structure of 14 C from the off-diagonal cross-shell interaction, 〈 pp V sdsd 〉, which represents the mixing between the 0 and 2 ħω configurations in the psd model space. The observed levels of the positive states in 14 C can be nicely described in 0–4 ħω or a larger model space through the well defined Hamiltonians, YSOX and WBP, with a reduction of the strength of the 〈 pp V sdsd 〉 interaction in the latter. The observed B (GT) values for 14 C can be generally described by YSOX, while WBP and their modifications of the 〈 pp V sdsd 〉 interaction fail for some values. Further investigation shows the effect of such interactions on the configuration mixing and occupancy. The present work shows examples of how the off-diagonal cross-shell interaction strongly drives the nuclear structure.

  • High cumulants of conserved charges and their statistical uncertainties
    • Authors: Chen Li-Zhu; Zhao Ye-Yin, Pan Xue, Li Zhi-Ming Wu Yuan-Fang
      First page: 104103
      Abstract: We study the influence of measured high cumulants of conserved charges on their associated statistical uncertainties in relativistic heavy-ion collisions. With a given number of events, the measured cumulants randomly fluctuate with an approximately normal distribution, while the estimated statistical uncertainties are found to be correlated with corresponding values of the obtained cumulants. Generally, with a given number of events, the larger the cumulants we measure, the larger the statistical uncertainties that are estimated. The error-weighted averaged cumulants are dependent on statistics. Despite this effect, however, it is found that the three sigma rule of thumb is still applicable when the statistics are above one million.

  • Isospin splitting of nucleon effective mass and symmetry energy in
           isotopic nuclear reactions
    • Authors: Ya-Fei Guo; Peng-Hui Chen, Fei Niu, Hong-Fei Zhang, Gen-Ming Jin Zhao-Qing Feng
      First page: 104104
      Abstract: Within an isospin and momentum dependent transport model, the dynamics of isospin particles (nucleons and light clusters) in Fermi-energy heavy-ion collisions are investigated for constraining the isospin splitting of nucleon effective mass and the symmetry energy at subsaturation densities. The impacts of the isoscalar and isovector parts of the momentum dependent interaction on the emissions of isospin particles are explored, i.e., the mass splittings of ##IMG## [] and ##IMG## [] ( ##IMG## [] ). The single and double neutron to proton ratios of free nucleons and light particles are thoroughly investigated in the isotopic nuclear reactions of 112 Sn+ 112 Sn and 124 Sn+ 124

  • A possible explanation of the knee of cosmic light component spectrum from
           100 TeV to 3 PeV
    • Authors: Wen-Hui Lin; Bi-Wen Bao, Ze-Jun Jiang Li Zhang
      First page: 105101
      Abstract: A mixed hydrogen and helium (H + He) spectrum with a clear steepening at ∼ 700 TeV has been detected by the ARGO-YBJ experiments. In this paper, we demonstrate that the observed H + He spectrum can be reproduced well with a model of cosmic rays escaping from the supernova remnants (SNRs) in our Galaxy. In this model, particles are accelerated in a SNR through a non-linear diffusive shock acceleration mechanism. Three components of high energy light nuclei escaped from the SNR are considered. It should be noted that the proton spectrum observed by KASCADE can be also explained by this model given a higher acceleration efficiency.

      Abstract: In this paper, we present a study of temperature effects on BGO calorimeters using proton MIPs collected in the first year of operation of DAMPE. By directly comparing MIP calibration constants used by the DAMPE data production pipe line, we find an experimental relation between the temperature and signal amplitudes of each BGO bar: a general deviation of −1.162%/°C, and −0.47%/°C to −1.60%/°C statistically for each detector element. During 2016, DAMPE’s temperature changed by ∼8°C due to solar elevation angle, and the corresponding energy scale bias is about 9%. By frequent MIP calibration operation, this kind of bias is eliminated to an acceptable value.

      Abstract: A software system has been developed for the DArk Matter Particle Explorer (DAMPE) mission, a satellite-based experiment. The DAMPE software is mainly written in C++ and steered using a Python script. This article presents an overview of the DAMPE offline software, including the major architecture design and specific implementation for simulation, calibration and reconstruction. The whole system has been successfully applied to DAMPE data analysis. Some results obtained using the system, from simulation and beam test experiments, are presented.

      Abstract: Transient beam loading is one of the key issues in any high beam current intensity superconducting accelerators, and needs to be carefully investigated. The core problem in the analysis is to obtain the time evolution of effective cavity voltage under transient beam loading. To simplify the problem, the second order ordinary differential equation describing the behavior of the effective cavity voltage is intuitively simplified to a first order one, with the aid of two critical approximations which lack proof of their validity. In this paper, the validity is examined mathematically in some specific cases, resulting in a criterion for the simplification. It is popular to solve the approximate equation for the effective cavity voltage numerically, while this paper shows that it can also be solved analytically under the step function approximation for the driven term. With the analytical solution to the effective cavity voltage, the transient reflected power from the cavity and the ...

  • Effect of cavity length detuning on the output characteristics for the
           middle infrared FEL oscillator of FELiChEM

      Abstract: FELiChEM is an infrared free electron laser (FEL) facility currently under construction, which consists of two oscillators generating middle-infrared and far-infrared laser covering the spectral range of 2.5–200 μm. In this paper, we numerically study the output characteristics of the middle-infrared oscillator with accurate cavity length detuning. Emphasis is put on the temporal structure of the micropulse and the corresponding spectral bandwidth. Taking the radiation wavelengths of 50 μm and 5 μm as examples, we show that the output pulse duration can be tuned in the range of 1–6 ps with corresponding bandwidth of 13%–0.2% by adjusting the cavity length detuning. In addition, a special discussion on the comb structure is presented, and it is indicated that the comb structure may arise in the output optical pulse when the normalized slippage length is much smaller than unity. This work has reference value for the operation of FELiChEM and other FEL oscillators.
