Abstract

We use the QCD sum rules to study possible B_c-like molecular states. We consider isoscalar J^P = 0⁺ and J^P = 1⁺ D^(∗)B^(∗) molecular currents. We consider the contributions of condensates up to dimension eight and we work at leading order in α_s . We obtain for these states masses around 7 GeV.
