Abstract:
The existence of doubly heavy flavor baryons has not been well established experimentally so far. In this Letter we systematically investigate the weak decays of the doubly charmed baryons, Ξcc++ and Ξcc+, which should be helpful for experimental sea...

2018, 42(5): 053102. doi: 10.1088/1674-1137/42/5/053102
Abstract:
We generalize several well known quantum equations to a Tsallis' q-scenario, and provide a quantum version of some classical fields associated with them in the recent literature. We refer to the q-Schrödinger, q-Klein-Gordon, q-Dirac, and q-Proca equ...
Super-light baryo-photons, weak gravity conjecture and exotic instantons in neutron-antineutron transitions

Abstract:
In companion papers A. Addazi, Nuovo Cim. C, 38(1):21 (2015), A. Addazi, Z. Berezhiani, and Y. Kamyshkov, arXiv:1607.00348, we have discussed current bounds on a new super-light baryo-photon, associated with a U(1)B-L gauge, from current neutron-anti...
Supersymmetric AdS4 vacua in N=3 gauged supergravity
Zhen-Bin Cao
2018, 42(5): 053104. doi: 10.1088/1674-1137/42/5/053104
Abstract:
We study the maximally supersymmetric AdS backgrounds of matter-coupled N=3 gauged supergravity in four dimensions. We find that to admit supersymmetric AdS vacua, the gauge group can only be of the form G0×HSO(3,n) with G0=SO(3), SO(3,1) or SL(3,R...
The DD* interaction with isospin zero in an extended hidden gauge symmetry approach
Bao-Xi Sun, Da-Ming Wan, Si-Yu Zhao
2018, 42(5): 053105. doi: 10.1088/1674-1137/42/5/053105
Abstract:
The DD* interaction via a ρ or ω exchange is constructed within an extended hidden gauge symmetry approach, where the strange quark is replaced by the charm quark in the SU(3) flavor space. With this DD* interaction, a bound state slightly lower than...

Abstract:
Static fission barriers for 95 even-even transuranium nuclei with charge number Z=94-118 have been systematically investigated by means of pairing self-consistent Woods-Saxon-Strutinsky calculations using the potential energy surface approach in mult...
Estimation of the chiral magnetic effect considering the magnetic field response of the QGP medium
Sheng-Qin Feng, Xin Ai, Lei Pei, Fei Sun, Yang Zhong, Zhong-Bao Yin
2018, 42(5): 054102. doi: 10.1088/1674-1137/42/5/054102
Abstract:
The magnetic field plays a major role in searching for the chiral magnetic effect in relativistic heavy-ion collisions. If the lifetime of the magnetic field is too short, as predicted by simulations of the field in vacuum, the chiral magnetic effect...
Crust-core properties of neutron stars in the Nambu-Jona-Lasinio model

2018, 42(5): 054103. doi: 10.1088/1674-1137/42/5/054103
Abstract:
We adopt the Nambu-Jona-Lasinio (NJL) model to study the crust-core transition properties in neutron stars (NSs). For a given momentum cutoff and symmetry energy of saturation density in the NJL model, decreasing the slope of the symmetry energy give...

Abstract:
The power index formula has been used to obtain the band head spin (I0) of all the superdeformed (SD) bands in Hg isotopes. A least squares fitting approach is used. The root mean square deviations between the determined and the observed transition e...

Within the framework of the isospin-dependent quantum molecular dynamics model, along with the GEMINI model, the 86Kr+181Ta reaction at 80, 120 and 160 MeV/nucleon and the 78Kr+181Ta reaction at 160 MeV/nucleon are studied, and the production cross s...
