      Abstract: The product of the ##IMG## [http://ej.iop.org/images/1674-1137/40/1/011001/cpc20160100ieqn4.gif] differential production cross-section and the branching fraction of the decay ##IMG## [http://ej.iop.org/images/1674-1137/40/1/011001/cpc20160100ieqn5.gif] is measured as a function of the beauty hadron transverse momentum, p T , and rapidity, y . The kinematic region of the measurements is p T < 20 GeV/ c and 2.0 < y < 4.5. The measurements use a data sample corresponding to an integrated luminosity of 3fb −1 collected by the LHCb detector in pp collisions at centre-of-mass energies ##IMG## [http://ej.iop.org/images/1674-1137/40/1/011001/cpc20160100ieqn6.gif] in 2011 and ##IMG## [http://ej.iop.org/images/1674-1137/40/1/011001/cpc20160100ieqn7.gif] in 2012.

  • Experimental review of e + e − →ππh c
    • Authors: Qing-ping Ji; Yu-Ping Guo, Ai-Qiang Guo, Chun-Xu Yu Zhi-Yong Wang
      First page: 012001
      Abstract: We review the recent BESIII measurement of e + e − → ππh c in which its line shape is studied between the center-of-mass energies of 3.9 to 4.42 GeV and an iso-vector charmonium-like state Z c (4020) is observed in the invariant mass of πh c at the BESIII experiment. The charged Z c (4020) ± is the second observed Z c state following Z c (3900), while the Z c (4020) 0 is the first observed neutral Z c state. The line shape of σ (e + e − → ππh c ) is also re-analyzed in view of searching for the Y state and the existence of the Y(4220) state is confirmed and compared with the previous work of the BESIII experiment.

           ηJ/ψ K ± and e + e – → η J /ψ
           processes
    • Authors: Xu-yang Gao; Xiao-long Wang Cheng-ping Shen
      First page: 013001
      Abstract: We search for the ψ(4 S ) state in the B ± → ηJ/ψ K ± and e + e – → ηJ/ψ processes based on the Belle measurements with the assumed mass M = (4230±8) MeV/ c 2 and width Γ = (38±12) MeV. No significant signal is observed in the ηJ/ψ mass spectra. The 90% confidence level upper limit on the product branching fraction ##IMG## [http://ej.iop.org/images/1674-1137/40/1/013001/cpc20160102ieqn28.gif] is obtained in the B ± → ηJ/ψ K ± decays. By assuming the partial width of ψ(4 S ) → e + e – to be 0.63 keV, a branching fraction limit ##IMG## [http://ej.iop.org/images/1674-1137/40/1/013001/cpc20160102ieqn29.gif] is obtained at the 90% confidence level in e + e – → ηJ/ψ, which is consistent with the theoretical prediction.

      Abstract: By assuming that the scalar meson ##IMG## [http://ej.iop.org/images/1674-1137/40/1/013101/cpc20160103ieqn2.gif] belongs to the first excited states or the lowest lying ground states of qq̄′, we study the pure annihilation-type decays ##IMG## [http://ej.iop.org/images/1674-1137/40/1/013101/cpc20160103ieqn3.gif] in the QCD factorization approach. Within the Standard Model, the branching fractions are of the order of 10 −8 –10 −7 , which is possible to measure in the ongoing LHCb experiment or forthcoming Belle-II experiment. We also study these decays in the family non-universal Z′ model. The results show that if m Z′ ≈ 600 GeV ( ζ = 0.02), both the branching fractions and CP asymmetries of ##IMG## [http://ej.iop.org/images/1674-1137/40/1/013101/cpc20160103ieqn4.gif] could be changed remarkably, which provides us with a place for probing the effect of new physi...

  • Method for measuring prompt γ -rays generated by D-T neutrons
           bombarding a depleted uranium spherical shell
    • Authors: Jian-Guo Qin; Cai-Feng Lai, Li Jiang, Rong Liu, Xin-Wei Zhang, Bang-Jiao Ye Tong-Hua Zhu
      First page: 014001
      Abstract: The prompt γ -ray spectrum from depleted uranium (DU) spherical shells induced by 14 MeV D-T neutrons is measured. Monte Carlo (MC) simulation gives the largest prompt γ flux with the optimal thickness of the DU spherical shells 3–5 cm and the optimal frequency of neutron pulse 1 MHz. The method of time of flight and pulse shape coincidence with energy (DC-TOF) is proposed, and the subtraction of the background γ -rays discussed in detail. The electron recoil spectrum and time spectrum of the prompt γ -rays are obtained based on a 2″×2″ BC501A liquid scintillator detector. The energy spectrum and time spectrum of prompt γ -rays are obtained based on an iterative unfolding method that can remove the influence of γ -rays response matrix and pulsed neutron shape. The measured time spectrum and the calculated results are roughly consistent with each other. Experimental prompt γ -ray spectrum in the 0.4–3 MeV energy region agrees well with MC...

  • Triaxial dynamics in the quadrupole-deformed rotor
    • Authors: Qiu-Yue Li; Xiao-Xiang Wang, Yan Zuo, Yu Zhang Feng Pan
      First page: 014101
      Abstract: The triaxial dynamics of the quadrupole-deformed rotor model of both the rigid and the irrotational type are investigated in detail. The results indicate that level patterns of the two types of model can be matched with each other to the leading order of the deformation parameter β . In particular, it is found that the dynamical structure of the irrotational type with most triaxial deformation ( γ = 30°) is equivalent to that of the rigid type with oblate deformation ( γ = 60°), and the associated spectrum can be classified into the standard rotational bands obeying the rotational L ( L +1)-law or regrouped into a new ground- and γ -band with odd–even staggering in the new γ -band, commonly recognized as a signature of the triaxiality. The differences between the two types of the model in this case are emphasized, especially in the E2 transitional characteristics.

  • Effect of long-range correlation on scaling behavior of normalized
           factorial moments for the first-order phase
    • Authors: Guang-Lei Li; Chun-Bin Yang
      First page: 014102
      Abstract: Within the framework of Ginzburg–Landau theory, the effect of multiplicity correlation between the dynamical multiplicity fluctuations is analyzed for a first-order phase transition from quark–gluon plasma to hadrons. Normalized factorial correlators are used to study the correlated dynamical fluctuations. A scaling behavior is found among the factorial correlators, and an approximate universal exponent, which is weakly dependent on the details of the phase transition, is obtained.

  • Spatial dependent diffusion of cosmic rays and the excess of primary
           electrons derived from high precision measurements by AMS-02
    • Authors: Chao Jin; Yi-Qing Guo Hong-Bo Hu
      First page: 015101
      Abstract: The precise spectra of Cosmic Ray (CR) electrons and positrons have been published by the measurement of AMS-02. It is reasonable to regard the difference between the electron and positron spectra (Δ Φ = Φ e − − Φ e + ) as being dominated by primary electrons. The resulting electron spectrum shows no sign of spectral softening above 20 GeV, which is in contrast with the prediction of the standard model of CR propagation. In this work, we generalize the analytic one-dimensional two-halo model of diffusion to a three-dimensional realistic calculation by implementing spatial variant diffusion coefficients in the DRAGON package. As a result, we can reproduce the spectral hardening of protons observed by several experiments, and predict an excess of high energy primary electrons which agrees with the measurement reasonably well. Unlike the break spectrum obtained for protons, the model calculation predicts a smooth electron exc...

  • Aging effect in the BESIII drift chamber
    • Authors: Ming-Yi Dong; Qing-Lei Xiu, Ling-Hui Wu, Zhi Wu, Zhong-Hua Qin, Pin Shen, Fen-Fen An, Xu-Dong Ju, Yi Liu, Kai Zhu, Qun Ou-Yang Yuan-Bo Chen
      First page: 016001
      Abstract: As the main tracking detector of BESIII, the drift chamber provides accurate measurements of the position and the momentum of the charged particles produced in e + e − collisions at BEPCII. After six years of operation, the drift chamber is suffering from aging problems due to huge beam-related background. The gains of the cells in the first ten layers show an obvious decrease, reaching a maximum decrease of about 29% for the first layer cells. Two calculation methods for the gain change (Bhabha events and accumulated charges with 0.3% aging ratio for inner chamber cells) give almost the same results. For the Malter effect encountered by the inner drift chamber in January 2012, about 0.2% water vapor was added to the MDC gas mixture to solve this cathode aging problem. These results provide an important reference for MDC operating high voltage settings and the upgrade of the inner drift chamber.

  • Some new progress on the light absorption properties of linear alkyl
           benzene solvent
    • Authors: Guang-You Yu; De-Wen Cao, Ai-Zhong Huang, Lei Yu, Chang-Wei Loh, Wen-Wen Wang, Zhi-Qiang Qian, Hai-Bo Yang, Huang Huang, Zong-Qiang Xu, Xue-Yuan Zhu, Bin Xu Ming Qi

      Abstract: Linear alkyl benzene (LAB) will be used as the solvent in a liquid scintillator mixture for the JUNO antineutrino experiment. Its light absorption properties should therefore be understood prior to its effective use in the experiment. Attenuation length measurements at a light wavelength of 430 nm have been performed on samples of LAB prepared for the JUNO experiment. Inorganic impurities in LAB have also been studied for their possibilities of light absorption in our wavelength of interest. In view of a tentative plan by the JUNO collaboration to utilize neutron capture with hydrogen in the detector, we also present in this work a preliminary study on the carbon–hydrogen ratio and the attenuation length of the samples.
