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…
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…
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…
Searching for compact pentaquark state within the bag model framework
Wen-Nian Liu, Wen-Xuan Zhang, Fu-Quan Dou
The search for the compact limit of multi-quark states is a challenging issue. Within the framework of the MIT bag model, we propose an effective limit bag radius of $R_{c} = 5.615…
