Abstract
The form factors of the semileptonic B-c -> S(AV)l nu (l = tau, mu, e) transitions, where S and AV denote the scalar X-c0 and axial vector (X-c1, h(c)) mesons, are calculated within the framework of the three-point QCD sum rules. The results of form factors are used to estimate the total decay widths and branching ratios of these transitions. A comparison of our results on branching ratios with the predictions of other approaches is also presented.
