Exotic B_c-like molecules in QCD Sum Rules [PDF]
Raphael M. Albuquerque, Xiang Liu, Marina NielsenWe 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.View original: http://arxiv.org/abs/1203.6569
