Semileptonic decay of $B_c$ meson into $c\bar{c}$ states in a QCD potential model

Abstract

The slope and curvature of Isgur Wise function for $B_c$ meson is computed in a QCD potential model in two different approaches of choosing the perturbative term of the Cornell potential. Based on heavy quark effective theory the exclusive semileptonic decay rates of $B_c$ meson into the $c\bar{c}({\eta }_c,J/\psi )$ states are exploited. Spin symmetry breaking effects are ignored upto a particular point and the form factors are connected with Isgur-Wise function for other kinematic point since the recoil momentum of $c\bar{c}$ from $B_c$ is small due to its heavy mass.

We are presently improving the manuscript
