Contribution

It introduces a field-theoretical framework to study open charm and bottom hadronic molecules, providing new insights into their possible formation and characteristics.

Findings

Identification of parameter space for bound states

Estimation of masses of $D^{(*)} B^{(*)}$-states

Discussion on the formation of loosely-bound molecules

Abstract

We perform a field-theoretical study of possible deuteron-like molecules with both open charm and bottom, using the Heavy-Meson Effective Theory. In this approach, we analyze the parameter space of the coupling constants and discuss the formation of loosely-bound $D^{(*)} B^{(*)} $-states. We estimate their masses and other properties.
