Exotic B_c-like molecules in QCD Sum Rules

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