Strangeness and baryon-baryon interactions in relativistic chiral effective field theory
Zhi-Wei Liu, Jing Song, Kai-Wen Li +1
The strangeness and baryon-baryon interactions are investigated in the relativistic chiral effective field theory at leading order. First, the potentials are derived fr…
interaction in leading order covariant chiral effective field theory
Jing Song, Yang Xiao, Zhi-Wei Liu +3
We study the interaction in the covariant chiral effective field theory (ChEFT) at leading order. All the relevant low-energy constants are determined by fitting to the lat…
Strangeness hyperon-nucleon interactions: chiral effective field theory vs. lattice QCD
Jing Song, Kai-Wen Li, Li-Sheng Geng
Hyperon-nucleon interactions serve as basic inputs to studies of hypernuclear physics and dense (neutron) stars. Unfortunately, a precise understanding of these important quantitie…
