Hadronic molecules with both open charm and bottom

TL;DR

This paper investigates the potential existence of $B_c$-like molecular states formed by S-wave charm and bottom mesons using a one-boson-exchange model, providing mass estimates and decay modes for future experiments.

Contribution

It introduces a study of $B_c$-like molecules considering S-D mixing effects, which is a novel application of the one-boson-exchange model to these systems.

Findings

Possible $B_c$-like molecular states identified

Mass estimates for these states provided

Decay modes suggested for experimental search

Abstract

With the one-boson-exchange model, we study the interaction between the S-wave $D^{(*)}/D^{(*)}_s$ meson and S-wave $B^{(*)}/B^{(*)}_s$ meson considering the S-D mixing effect. Our calculation indicates that there may exist the $B_c$-like molecular states. We estimate their masses and list the possible decay modes of these $B_c$-like molecular states, which may be useful to the future experimental search.
