Double-heavy tetraquarks with strangeness in the chiral quark model
Xiaoyun Chen, Fu-Lai Wang, Yue Tan +1
Recently, some progresses have been made on the double-heavy tetraquarks in the experiments, such as reported by LHCb Collaboration, and reported by…
Doubly heavy tetraquark states and
Xiaoyun Chen
Inspired by the recent observation of a very narrow state, called , by the LHCb collaboration, the possible bound states and low-lying resonance states of the doubly heav…
Dynamical study of -wave system
You-Chang Yang, Zhi-Yun Tan, Hong-Shi Zong +1
We perform the energy spectra calculating for the -wave (where and ) system within two constituent quark models. The bound states of $B^*\bar…
Possible and molecular states in the extended constituent quark models
You-Chang Yang, Zhi-Yun Tan, Jialun Ping +1
The possible neutral and molecular states are studied in the framework of the constituent quark models, which is extended by including…
The chiral phase transition with a chiral chemical potential in the framework of Dyson-Schwinger equations
Shu-Sheng Xu, Zhu-Fang Cui, Bin Wang +3
Within the framework of Dyson-Schwinger equations (DSEs), we discuss the chiral phase transition of QCD with a chiral chemical potential as an additional scale. We focus espe…
Dynamical chiral symmetry breaking in the NJL model with a constant external magnetic field
Song Shi, You-Chang Yang, Yong-Hui Xia +3
In this paper we develop a new method that is different from Schwinger proper time method to deduce the fermion propagator with a constant external magnetic field. In the NJL model…
