Abstract

The form factors of the semileptonic $\chi_{b2}(1P)\rightarrow B_{c}\bar{l}\nu$ decay are calculated using the QCD sum rule approach. The results obtained are then used to estimate the decay widths of this transition in all lepton channels. The orders of decay rates indicate that this transition is accessible at LHC for all lepton channels.
