Description

We proposed a unified framework to describe the interactions of the observed $T_{cc}$, $P_c$, and $P_{cs}$ within a quark level interaction. We predict the possible $D^{(*)}_{(s)}D^{(*)}_{(s)}$ molecular states in the SU(3) limit with the masses of the $P_c$ states as the inputs. We also investigate the baryon-meson and baryon-baryon systems. We suggest that for a specific heavy flavor meson-meson, baryon-meson, or baryon-baryon system, the interactions for the states with the same flavor and spin matrix elements can be related by a generalized flavor-spin symmetry.

Summary

The obtained results to the observed $P_c$, $P_{cs}$, and $T_{cc}$ states indicate that the interactions of heavy flavor di-hadron systems may have a heavy quark spin and flavor symmetry. Specifically, the spin multiplets in the same system obey the heavy quark spin symmetry, for example, the $P_{c}(4312)$, $P_{c}(4440)$, and $P_{c}(4457)$. While different heavy flavor di-hadron systems obey the heavy quark flavor symmetry, for example, the observed $P_{c}$, $P_{cs}$, and $T_{cc}$ states.
