PARTICLES AND FIELDS
Strong decays of P-wave mixing heavy-light 1+ states
Zhi-Hui Wang, Yi Zhang, Tian-Hong Wang, Yue Jiang, Qiang Li, Guo-Li Wang
2018, 42(12): 123101. doi: 10.1088/1674-1137/42/12/123101
Abstract:
Many P-wave mixing heavy-light 1+ states have not yet been discovered by experiment, while others have been discovered but without width information, or with large uncertainties on the widths. In this paper, the strong decays of the P-wave mixing hea...
Weak decays of doubly heavy baryons: “decay constants”
Xiao-Hui Hu, Yue-Long Shen, Wei Wang, Zhen-Xing Zhao
2018, 42(12): 123102. doi: 10.1088/1674-1137/42/12/123102
Abstract:
Inspired by the recent observation of the Ξcc++ by the LHCb Collaboration, we explore the "decay constants" of doubly heavy baryons in the framework of QCD sum rules. With the Ξcc, Ξbc, Ξbb, and Ωcc, Ωbc, Ωbb baryons interpolated by three-quark opera...
Pseudo-rapidity distribution from a perturbative solution of viscous hydrodynamics for heavy ion collisions at RHIC and LHC

2018, 42(12): 123105. doi: 10.1088/1674-1137/42/12/123105
Abstract:
We discuss some thermodynamical features of a QCD system within the two-flavor Polyakov loop extended Nambu—Jona-Lasinio (PNJL) model. Several thermodynamical quantities of interest (pressure, energy density, specific heat, speed of sound, etc.) are ...
A model with flavor-dependent gauged U(1)B-L1×U(1)B-L2-L3 symmetry
Linping Mu, Hiroshi Okada, Chao-Qiang Geng
2018, 42(12): 123106. doi: 10.1088/1674-1137/42/12/123106
Abstract:
We propose a new model with flavor-dependent gauged U(1)B-L1×U(1)B-L2-L3 symmetry in addition to the flavor-blind symmetry in the Standard Model. The model contains three right-handed neutrinos to cancel gauge anomalies and several Higgs bosons to co...
Probing top-quark couplings indirectly at Higgs factories
Gauthier Durieux, Jiayin Gu, Eleni Vryonidou, Cen Zhang
2018, 42(12): 123107. doi: 10.1088/1674-1137/42/12/123107
Abstract:
We perform a global effective-field-theory analysis to assess the combined precision of Higgs couplings, triple gauge-boson couplings, and top-quark couplings, at future circular e+e- colliders, with a focus on runs below the tt production threshold....
Correlation of normal neutrino mass ordering with upper octant of θ23 and third quadrant of δ via RGE-induced μ-τ symmetry breaking
Guo-yuan Huang, Zhi-zhong Xing, Jing-yu Zhu
2018, 42(12): 123108. doi: 10.1088/1674-1137/42/12/123108
Abstract:
The recent global analysis of three-flavor neutrino oscillation data indicates that the normal neutrino mass ordering is favored over the inverted one at the 3σ level, and the best-fit values of the largest neutrino mixing angle θ23 and the Dirac CP-...
R4 corrections to holographic Schwinger effect
Fei Li, Zi-qiang Zhang, Gang Chen
2018, 42(12): 123109. doi: 10.1088/1674-1137/42/12/123109
Abstract:
We consider R4 corrections to the holographic Schwinger effect in an AdS black hole background and a confining D3-brane background. The potential between a test particle pair are performed for both backgrounds. We find there is no potential barrier i...
Conformal field theory on the horizon of a BTZ black hole
Jing-Bo Wang, Chao-Guang Huang
2018, 42(12): 123110. doi: 10.1088/1674-1137/42/12/123110
Abstract:
In a three-dimensional spacetime with negative cosmological constant, general relativity can be written as two copies of SO(2,1) Chern-Simons theory. On a manifold with a boundary, the Chern-Simons theory induces a conformal field theory—Wess-Zumino-...

Abstract:
The nuclear electric quadrupole moment (NQM) is one of the fundamental bulk properties of the nucleus with which nuclear deformations can be investigated. The number of measured NQMs is significantly less than that of known masses, and there is still...

A cosmic-ray muon telescope has been collecting data since the end of 2014, which was shortly after the telescope was built in the Zhongshan Station of Antarctica. The telescope is the first observation device to be built by Chinese scientists in Ant...
