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…
Radiative Decays of Vector Mesons with Light-Cone Sum Rules
Zhi Jun Wang, Di Gao, Kai Kai Zhang +2
Hadronic electromagnetic form factors and radiative decay properties offer a crucial window into the nonperturbative dynamics of Quantum chromodynamics (QCD). In this work, we empl…
Resonant Singly Heavy Pentaquarks in the MIT Bag Model: Mass Spectra and Strong Decays
Wen-Nian Liu, Wen-Xuan Zhang, Cheng-Jie Wang +2
Exploring the limits of color interactions in multiquark states is an important topic. Based on the bag confinement picture of hadrons, we find that for singly heavy pentaquarks, t…
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…
