Abstract
We employ QCD sum rules to calculate the leptonic decay constant of the D2⁎(2460) tensor meson and the transition form factors of the semileptonic B→D2⁎(2460)ℓν¯(ℓ=τ,μ,e) decay channel. Using the fit functions of the form factors, we estimate the total decay widths and branching ratios of this transition at all lepton channels. The order of branching ratio indicates that this channel can be detected at LHC.
