Abstract

We first investigate the semileptonic annihilation decay B_c \to \eta' l\nu in QCD. We find that the η′\eta' momentum distribution is peaked within its small recoil region due to the loop effects. The branching ratio is estimated to be Br(Bc→η′lν)=1.6×10−4 Br(B_c \to \eta' l\nu)=1.6\times 10^{-4} for l=μ,el=\mu,e, which is accessible at CERN LHC.
