Magnetic moments of the spin-1/2 singly charmed baryons in covariant baryon chiral perturbation theory
Shi-Rui Xiabng, Yang Xiao, Li-Sheng Geng
Recent experimental advances have reignited theoretical interests in heavy-flavor hadrons. In this work, we study the magnetic moments of the spin-1/2 singly charmed baryons up to…
Meson-baryon scattering up to the next-to-next-to-leading order in covariant baryon chiral perturbation theory
Jun-Xu Lu, Li-Sheng Geng, Xiu-Lei Ren +1
We study the scattering of a pseudoscalar meson off one ground state octet baryon in covariant baryon chiral perturbation theory (BChPT) up to the next-to-next-to-leading order. Th…
Covariant chiral nucleon-nucleon contact Lagrangian up to order
Yang Xiao, Li-Sheng Geng, Xiu-Lei Ren
We adopt a covariant version of the naive dimensional analysis and construct the chiral two-nucleon contact Lagrangian constrained by Lorentz, parity, charge conjugation, hermitian…
Strong decays of the as a molecule
Yin Huang, Cheng-jian Xiao, Li-Sheng Geng +1
We study the strong decays of the newly observed assuming that it is a pure molecular state. Considering four possible spin-parity assingments $J^P=1/2^{\p…
Bound state formation in the system
A. Martinez Torres, K. P. Khemchandani, Li-Sheng Geng
We study the system in a coupled channel approach, by including and , and find that the dynamics involved in the system forms a bound state with isospin …
Magnetic moments of the spin-1/2 doubly charmed baryons in covariant baryon chiral perturbation theory
Ming-Zhu Liu, Yang Xiao, Li-Sheng Geng
Inspired by the recent discovery of the by the LHCb Collaboration, we study the magnetic moments of the spin-1/2 doubly charmed baryons up to the next-to-leading orde…
