Fully strange tetra- and penta-quarks in a chiral quark model
Gang Yang, Jialun Ping, Jorge Segovia
Motivated by the recently reported resonant structure , a strong candidate for a fully strange tetraquark with positive parity, we perform a systematic study of fully stra…
Triply heavy tetraquarks and in a constituent quark model
Gang Yang, Jialun Ping, Jorge Segovia
A systematic investigation of -wave triply heavy tetraquark systems with quark content and , spin-parity quantum numbers $…
Triply charm and bottom tetraquarks in a constituent quark model
Gang Yang, Jialun Ping, Jorge Segovia
Singly, doubly and fully charmed tetraquark candidates, \emph{e.g.}, , and have been recently reported by the LHCb collaboration. The…
Probing axion-like particles in leptonic decays of heavy mesons
Gang Yang, Tianhong Wang, Guo-Li Wang
We study the possibility of finding the axion-like particles (ALPs) through the leptonic decays of heavy mesons. The Standard Model (SM) predictions of the branching ratios of the…
The tetraquark system in a chiral quark model
Gang Yang, Jialun Ping, Jorge Segovia
Inspired by the experimentally reported exotic states, the -wave tetraquarks, with spin-parity , and…
Hidden-charm pentaquarks with strangeness in a chiral quark model
Gang Yang, Jialun Ping, Jorge Segovia
The LHCb collaboration has recently announced the discovery of two hidden-charm pentaquark states with also strange quark content, and ; its analysis p…
