  • Cluster decay of the high-lying excited states in 14 C
    • Authors: Z. Y. Tian; Y. L. Ye, Z. H. Li, C. J. Lin, Q. T. Li, Y. C. Ge, J. L. Lou, W. Jiang, J. Li, Z. H. Yang, J. Feng, P. J. Li, J. Chen, Q. Liu, H. L. Zang, B. Yang, Y. Zhang, Z. Q. Chen, Y. Liu, X. H. Sun, J. Ma, H. M. Jia, X. X. Xu, L. Yang, N. R. Ma L. J. Sun

      Abstract: A cluster-transfer experiment of 9 Be( 9 Be, 14 C → α + 10 Be) α at an incident energy of 45 MeV was carried out in order to investigate the molecular structure in high-lying resonant states in 14 C. This reaction is of extremely large Q -value, making it an excellent case to select the reaction mechanism and the final states in outgoing nuclei. The high-lying resonances in 14 C are reconstructed for three sets of well discriminated final states in 10 Be. The results confirm the previous decay measurements with clearly improved decay-channel selections and also show a new state at 23.5(1) MeV. The resonant states at 22.4(3) and 24.0(3) MeV decay primarily into the typical molecular states at about 6 MeV in 10 Be, indicating a well developed cluster structure in these high-lying states in 14 C. Further measurements of more states of this kind are suggested.

      Abstract: By analyzing 2.93 fb −1 data collected at the center-of-mass energy ##IMG## [] with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D + → K̅ 0 e + ν e to be ℬ( D + → K̅ 0 e + ν e ) = (8.59 ± 0.14 ± 0.21)% using ##IMG## [] , where the first uncertainty is statistical and the second systematic. Our result is consistent with previous measurements within uncertainties..

  • Tuning and validation of hadronic event generator for R value measurements
           in the tau-charm region
    • Authors: Rong-Gang Ping; Xi-An Xiong, Lei Xia, Zhen Gao, Ying-Tian Li, Xing-Yu Zhou, Bing-Xin Zhang, Bo Zheng, Wen-Biao Yan, Hai-Ming Hu Guang-Shun Huang
      First page: 113002
      Abstract: To measure the R value in an energy scan experiment with e + e − collisions, precise calculation of initial state radiation is required in the event generators. We present an event generator for this consideration, which incorporates initial state radiation effects up to second order accuracy. The radiative correction factor is calculated using the totally hadronic Born cross section. The measured exclusive processes are generated according to their cross sections, while the unknown processes are generated using the LUND Area Law model, and its parameters are tuned with data collected at ##IMG## [] . The optimized values are validated with data in the range ##IMG## [] . These optimized parameters are universally valid for event generation below the DD̅ threshold.

  • A mass reconstruction technique for a heavy resonance decaying to τ +
           τ −
    • Authors: Li-Gang Xia
      First page: 113003
      Abstract: For a resonance decaying to τ + τ − , it is difficult to reconstruct its mass accurately because of the presence of neutrinos in the decay products of the τ leptons. If the resonance is heavy enough, we show that its mass can be well determined by the momentum component of the τ decay products perpendicular to the velocity of the τ lepton, p ⊥ , and the mass of the visible/invisible decay products, m vis/inv , for τ decaying to hadrons/leptons. By sampling all kinematically allowed values of p ⊥ and m vis/inv according to their joint probability distributions determined by the MC simulations, the mass of the mother resonance is assumed to lie at the position with the maximal probability. Since p ⊥ and m vis/inv are invariant under the boost in the τ lepton direction, the joint probability distributions are...

  • Thermodynamic surface system of static black holes and area law
    • Authors: Ming Chen; Yong-Chang Huang
      First page: 113101
      Abstract: We propose a new picture of black holes through a special holographic screen. This holographic screen contains all the degrees of freedom of a black hole. We find that this holographic screen is similar to the ordinary thermodynamic surface system. Meanwhile, through the “white-wall box” and the formula of sound velocity, we find some similarities between gravitons and photons. We further assume that such a holographic screen is a kind of Bose-Einstein condensate of gravitons. Through this assumption and those similarities, we finally get the area law of static black holes.

  • Gauge theory of massless spin-
           ##IMG## []
           field in de Sitter space-time
    • Authors: S. Parsamehr; M. Mohsenzadeh
      First page: 113102
      Abstract: On several levels of theoretical physics, especially particle physics and early universe cosmology, de Sitter space-time has become an attractive possibility. The principle of local gauge invariance governs all known fundamental interactions of elementary particles, from electromagnetism and weak interactions to strong interactions and gravity. This paper presents a procedure for defining the gauge-covariant derivative and gauge invariant Lagrangian density in de Sitter ambient space-time formalism. The gauge invariant field equation is then explicitly calculated in detail for a massless spin- ##IMG## [] gauge field.

  • A possible interpretation of the Higgs mass by the cosmological attractive
    • Authors: Fa-Peng Huang; Yifu Cai, Hong Li Xinmin Zhang
      First page: 113103
      Abstract: Recently, a novel idea [1] has been proposed to relax the electroweak hierarchy problem through the cosmological inflation and the axion periotic potential. Here, we further assume that only the attractive inflation is needed to explain the light mass of the Higgs boson, where we do not need a specified periodic potential of the axion field. Attractive inflation during the early universe drives the Higgs boson mass from the large value in the early universe to the small value at present, where the Higgs mass is an evolving parameter of the Universe. Thus, the small Higgs mass can technically originate from the cosmological evolution rather than dynamical symmetry or anthropics. Further, we study the possible collider signals or constraints at a future lepton collier and the possible constraints from the muon anomalous magnetic moment. A concrete attractive relaxion model is also discussed, which is consistent with the data of Planck 2015.

  • SUSY effects in Higgs production at high energy e + e − colliders

      Abstract: Considering the constraints from collider experiments and dark matter detection, we investigate the SUSY effects in the Higgs production channels e + e − → Zh at an e + e − collider with a center-of-mass energy above 240 GeV and γγ → h → bb̄ at a photon collider with a center-of-mass energy above 125 GeV. In the parameter space allowed by current experiments, we find that the SUSY corrections to e + e − → Zh can reach a few percent and the production rate of γγ → h → bb̄ can be enhanced by a factor of 1.2 over the SM prediction. We also calculate the exotic Higgs production e + e − → Zh 1 in the next-to-minimal supersymmetric model (NMSSM) (h is the SM-like Higgs, h 1 is the CP-even Higgs bosons which can be much lighter than h). We find that at a 250 GeV e + e − collider the production rates of e + e − → Zh 1 can reach...

  • Self-consistent analysis of sub-barrier fusion enhancement effect in Ca +
           Ca and Ni + Ni
    • Authors: Nan-Ru Ma; Hui-Ming Jia, Cheng-Jian Lin, Lei Yang, Xin-Xing Xu, Li-Jie Sun, Feng Yang, Zhen-Dong Wu, Huan-Qiao Zhang, Zu-Hua Liu Dong-Xi Wang

      Abstract: The fusion dynamic mechanism of heavy ions at energies near the Coulomb barrier is complicated and still not very clear up to now. Accordingly, a self-consistent method based on the CCFULL calculations has been developed and applied for an ongoing study of the effect of the positive Q -value neutron transfer (PQNT) channels in this work. The typical experimental fusion data of Ca + Ca and Ni + Ni is analyzed within the unified calculation scheme. The PQNT effect in near-barrier fusion is further confirmed based on the self-consistent analysis and extracted quantitatively.

      Abstract: The target thickness for nitrogen was determined from the beam energy loss in HIRFL-CSRe during the experimental study of the K-REC process in 197 MeV/u Xe 54+ -N 2 collisions. Furthermore, the corresponding integrated luminosity of (1.15±0.06) × 10 30 cm −2 was obtained. As an independent check on the energy-loss method, we have also determined the integrated luminosity by measuring the produced X-rays from the K-REC process with a known differential cross section. The values of (1.12±0.06) × 10 30 and (1.09±0.06) × 10 30 cm −2 were obtained by using two high-purity germanium (HPGe) detectors which were oriented at 90° and 120° with respect to the beam path, respectively. The consistent results confirmed the feasibility of the energy-loss method, which may have an important impact on future internal target experiments at HIRFL-CSRe.
