Searching for bound states in the open strangeness systems

TL;DR

This paper investigates open strangeness systems using vector meson exchange potentials, dynamically generating known resonances and predicting new exotic states, while addressing the left-hand cut issues in scattering amplitudes.

Contribution

It introduces a systematic framework for analyzing open strangeness interactions and dynamically generates several known and new exotic resonances.

Findings

Dynamically generated resonances: $X_0(2866)$, $D^*_{s0}(2317)$, $D_{s1}(2460)$

Prediction of new exotic states in open strangeness systems

Detailed discussion of left-hand cut problems in scattering channels

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 heavy sector (no beauty quark), 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, there are many new exotics predicted. In addition, the left-hand cut problem in $t$- and $u$-channels is discussed in detail.
