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

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(⁎)D(⁎)B(⁎)-states. We estimate their masses and other properties.
