Multiple charm and hidden charm mesons with strangeness

TL;DR

This paper predicts new charm and hidden charm meson states with strangeness using a three-body system approach, highlighting potential discoveries that could deepen understanding of strong interactions involving heavy quarks.

Contribution

The study introduces novel predictions of charm and hidden charm mesons with strangeness using a three-body system model, not previously reported.

Findings

Prediction of a charm +2, isospin 1/2, strangeness +1 state at 4140 MeV

Prediction of a hidden charm $K^*$ state at 4307 MeV

Emphasis on experimental verification to understand strong interactions with heavy quarks

Abstract

In this talk we summarize our latest results on the study of three-body systems with explicit/hidden charm and with strangeness. In particular, we focus on the $K D D $ and $K D\bar D^*$ systems, where a charm $+2$, isospin $1/2$ and strangeness $+1$ state is found with a mass around 4140 MeV in the former and a $K^*$ state, with hidden charm, at a mass around 4307 MeV is obtained in the latter. Both states are predictions of our model and the experimental confirmation of them would be important to understand the properties of the strong interaction in the presence of heavy quarks.
