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 t...

Zusammenfassung: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.
