$P_{c\bar{c}s}(4459{)}^0$, $P_{c\bar{c}s}(4338{)}^0$ and mass spectrum of strange hidden-charm pentaquarks

Zhe-Hao Cao, Zhi-Yuan Chen, You-You Lin +2

Strange hidden-charm pentaquark states have been systematically investigated within a diquark-triquark model. Through a Gaussian expansion method, masses of some diquarks, triquark…
