ABSTRACT

We present the semileptonic decay of Bc meson in a QCD potential model with the coulombic part of the Cornell potential -4α^s/3r+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 Bc meson to its S wave charmonium states. Numerical estimates of widths for the transitions of B_c→J|ψ(η_c)lv₁ are presented.
