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 c (η_c,J/ψ) 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 c from B_c is small due to its heavy mass.
