Abstract

We calculate the transition form factors of the semileptonic B_c→ χ_c2 l ν in the framework of QCD sum rules taking into account the two-gluon condensate corrections. Using the obtained results of form factors we estimate the decay widths and branching ratios related to this transition at all lepton channels. A comparison of the obtained results with the predictions of other non-perturbative approaches are also made. The orders of branching ratios for different lepton channels indicate that the B_c→ χ_c2 l ν transition can be studied at LHC using the collected or future data.
