Exotic B_c-like molecules in QCD Sum Rules
We use the QCD sum rules to study possible -like molecular states. We
consider isoscalar and molecular
currents. We consider the contributions of condensates up to dimension eight
and we work at leading order in . We obtain for these states
masses around 7 GeV.Comment: 7 pages, 6 figures. Accepted for publication in Physics Letters B.
