Vacuum fluctuation effects on hyperonic neutron star matter
M. -H. Weng, X. -H. Guo, B. Liu
The vacuum fluctuation (VF) effects on the properties of the hyperonic neutron star matter are investigated in the framework of the relativistic mean field (RMF) theory. The VF cor…
Some mass relations for mesons and baryons in Regge phenomenology
Xin-Heng Guo, Ke-Wei Wei, Xing-Hua Wu
In the quasilinear Regge trajectory ansatz, some useful linear mass inequalities, quadratic mass inequalities and quadratic mass equalities are derived for mesons and baryons. Base…
Realistic Earth matter effects and a method to acquire information about small θ_{13} in the detection of supernova neutrinos
Xin-Heng Guo, Ming-Yang Huang, Bing-Lin Young
In this paper, we first calculate the realistic Earth matter effects in the detection of type II supernova neutrinos at the Daya Bay reactor neutrino experiment which is currently…
Strong decays of heavy baryons in Bethe-Salpeter formalism
Xin-Heng Guo, Ke-Wei Wei, Xing-Hua Wu
In this paper we study the properties of diquarks (composed of and/or quarks) in the Bethe-Salpeter formalism under the covariant instantaneous approximation. We calculate…
The Average Kinetic Energy of the Heavy Quark in in the Bethe-Salpeter Equation Approach
Xin-Heng Guo, Heng-Kui Wu
In the previous paper, based on the heavy quark symmetries of the QCD Lagrangian in the heavy quark limit, the Bethe-Salpeter equation for the heavy bar…
Studying the scalar bound states of the system in the Bethe-Salpeter formalism
Xin-Heng Guo, Xing-Hua Wu
We study the possible bound states of the system in the Bethe-Salpeter formalism in the ladder and instantaneous approximations. We find that the bound states exist. Howe…
