# $P_c$ Resonances in the Compact Pentaquark Picture

## Speakers

• Mr. Wiriya RUANGYOO

## Abstract

The study of $P_c$ resonances in the compact pentaquark picture is performed in quark model and group theory. It is found that there are totally 17 possible compact pentaquark states, where the hidden heavy pentaquark states may take the color singlet-singlet and color octet-octet configurations. The partial widths of strong decay indicate that $P_c(4440)$ may not be a compact pentaquark state while $P_c(4312)$ and $P_c(4457)$ could be the spin-$\frac{1}{2}$ and spin-$\frac{3}{2}$, respectively.
