Searching for bound states in the open strangeness systems

Abstract

Inspired by the recent findings of \(Z_{cs}\) and \(P_{cs}\) states, we investigate the strong interactions of the systems with open strangeness(es) from the light sector to the charm sector, where the interaction potential is derived from the vector meson exchange mechanism in t- and u-channels. In the current work, we discuss all of single channel cases for the open strangeness in the systemic framework, where the resonances \(X_0(2866)\), \(D^*_{s0}(2317)\) and \(D_{s1}(2460)\) are dynamically generated. Furthermore, some new bound systems are found from the single channel interaction. In addition, the left-hand cut problem in t- and u-channels is discussed in detail.
