Abstract

We first investigate the semileptonic annihilation decay B c → ηlν̄ in QCD. We find the η momentum distribution is peaked within its small recoil region due to the loop effects. The branching ratio is estimated to be Br(B c → ηlν̄) = 1.6 × 10 for l = μ, e, which is accessible at CERN LHC. PACS numbers 14.40 Nd 13.20 He 13.30 Ce 12.38.Bx JSPS Fellow sugamoto… (More)
