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…
Transition form factors for to from light-cone QCD sum rules
Di Gao, Jiangshan Lan, Duojie Jia +2
We apply the light-cone QCD sum rules with chiral currents to compute transition form factors of the semileptonic decay of the charmed and bottom scalar mesons to $a_{0}(980)…
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…
