Chiral mass corrections to decuplet hidden-charm pentaquark states

We calculate the masses of the $J^P=\frac{1}{2}^-$ hidden-charm pentaquark states in the $SU(3)$ decuplet within the heavy pentaquark chiral perturbation theory (HPChPT) up to the next-to-leading order (NLO). The one-loop self-energy corrections from the $\pi$, $K$, and $\eta$ mesons are evaluated. Taking $P_\psi^N(431...
