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…

Prospects for compact hexaquarks under the limitation imposed by quark confinement
Wen-Xuan Zhang, Wen-Nian Liu, Duojie Jia
The limitation of flavor constituents for compact multiquarks is crucial for understanding the strong interaction at the low energy scale. Utilizing the MIT bag model that incorpor…

Systematics of doubly heavy tetraquarks: nonstrange and strange
Kai-Kai Zhang, Wen-Xuan Zhang, Duojie Jia
Masses, magnetic moments and color-spin structures of nonstrange and strange tetraquarks with two heavy quarks are systematically studied in QCD string picture with chromomagnetic…
