We analyze the semileptonic Bₛ → Dₛ₂*(2573)ℓνℓ transition, where ℓ=τ, μ or e, within the standard model. We apply the QCD sum rule approach to calculate the transition form factors entering the low energy Hamiltonian defining this channel. The fit functions of the form factors are used to estimate the total decay widths and branching fractions in all lepton channels. The orders of branching ratios indicate that this transition is accessible at LHCb in near future.
