The $q ˉ q s ˉ Q$ $(q = u, d; Q = c, b)$ tetraquark system in a chiral quark model

Gang Yang, Jialun Ping, Jorge Segovia

Inspired by the experimentally reported $T_{c s ˉ} (2900)$ exotic states, the $S$ -wave $q ˉ q s ˉ Q$ $(q = u, d; Q = c, b)$ tetraquarks, with spin-parity $J^{P} = 0^{+}$ , $1^{+}$ 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, $P_{cs} (4338)$ and $P_{cs} (4459)$ ; its analysis p…
