Abstract

We present the semileptonic decay of B_c meson in a QCD potential model with the coulombic part of the Cornell potential -\frac4α_S3r+br+c as perturbation. Computing the slope and curvature of Isgur Wise function in this approach, we study the pseudoscalar and vector form factors for the transition of B_c meson to its S wave charmonium cc states. Numerical estimates of widths for the transitions of B_c→ J/ψ(η_c)lν_l are presented. The results are found to be in good agreement with other theoretical values.
