Compactness, mass spectra, and strong stability of singly heavy tetraquarks
Wen-Nian Liu, Kai-Kai Zhang, Duo-Jie jia +1
We propose a Coulomb-like parameterization in terms of bag radius of the short-range chromo-electric interaction between heavy quarks and strange quarks within the framework of the…

Mass relations in heavy hadrons from Jensen-like inequalities
Wen-Xuan Zhang, Wen-Nian Liu, Duojie Jia
We demonstrate that mass inequalities for hadrons with one or more heavy quarks arise primarily from the concavity of binding energies in the quark model, reflecting short-range Co…
