Abstract

We give a review and present a comprehensive calculations for the leptonic constant B_c of the low-lying pseudoscalar and vector states of B_c-meson in the framework of static and QCD-motivated nonrelativistic potential models taking into account the one-loop and two-loop QCD corrections in the short distance coefficient that governs the leptonic constant of B_c quarkonium system. Further, we use the scaling relation to predict the leptonic constant of the nS-states of the b%c system. Our results are compared with other models to gauge the reliability of the predictions and point out differences.
