Semileptonic decay of Bc meson into c c states in a QCD potential model
Abstract
The slope and curvature of Isgur Wise function for Bc 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 Bc meson into the c c\ (ηc,J/) 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 Bc is small due to its heavy mass.
