Exploring the mass spectrum and electromagnetic property of the ΞccK(*) and

Abstract

Using the one-boson-exchange model, we investigate the interactions between the doubly charmed baryon Ξcc(3621) and the S wave (anti-)kaon accounting for the S−D wave mixing and coupled-channel effects. We find the coupled ΞccK/ΞccK* state with I(JP)=0(1/2−), the ΞccK* state with 0(1/2−), the ΞccK¯ state with 0(1/2−), and the ΞccK¯* states with 0(1/2−,3/2−) can be recommended as good doubly charmed molecular candidates with strangeness |S|=1. We further examine their M1 radiative decay behaviors and magnetic moments within the constituent quark model framework. This information can enhance our understanding of their inner structures, including the distribution of electric charge and the orientation of the constituent quarks’ spins.
