Chiral symmetry and its spontaneous breaking play an important role both in the light hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …
There are eighteen possibly existing D (*) D¯(*), D (*) K¯(*), and D (*) D s (*)-hadronic molecular states. We construct their corresponding interpolating currents and calculate their …
Inspired by the observation of the doubly charmed state T cc and following theoretical studies on its spectroscopic parameters, we investigate its magnetic dipole moment …
The hidden-charm tetraquarks with strangeness, cc¯ sq¯(q= u, d), in JP= 0+, 1+, and 2+ are systematically investigated in the framework of real-and complex-scaling range of a chiral …
Recently, the hidden charm tetraquark states Z cs (3985) and Z cs (4000) with strangeness were observed by the BESIII and LHCb collaborations, respectively, which are great …
In the present work, we investigate the η c K, J/ψ K, η c K*, and J/ψ K* hidden-charm decay modes for the cc¯ su¯ four-quark system in the molecular and compact tetraquark scenarios …
In this study, we use the molecular and diquark-antidiquark tetraquark pictures to investigate magnetic and quadrupole moments of the B c-like ground state tetraquarks with the QCD …

We perform an effective field theory-based coupled-channel analysis of the recent BES III data on the e+ e-annihilation into the final state K+(D sD* 0+ D s*-D 0) in a wide energy …

Inspired by the detection of T cc tetraquark state by LHCb Collaboration, we perform a systemical investigation of the low-lying doubly heavy charm tetraquark states with …
