Two-body strong decays of the $P_{cs}(4338)$ as a hidden-charm pentaquark state via the QCD sum rules
In this work, we study the hadronic coupling constants of the $P_{cs}(4338)$ as a $[us][dc]\bar{c}-[ds][uc]\bar{c}$ type pentaquark state with the spin-parity $J^P={\frac{1}{2}}^-$ via the three-point QCD sum rules according to rigorous quark-hadron quality. We select the optimal parametrization to subtract contaminati...
