Hadronic states with both open charm and bottom in effective field theory

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 $D^{(\ast )}{B}^{(\ast )}$-states. We estimate their masses and other properties.
