We study the exclusive semileptonic rare Bc+→D+νν¯ decay in the framework of light-cone quark model. The transition form factors f+(q2) and fT(q2) are evaluated in the timelike region using the analytic continuation method in q+=0 frame. The analytic solutions of these form factors are compared with the results obtained from the double pole parametric form. The branching ratio for Bc+→D+νν¯ decay is calculated and compared with the other theoretical model predictions. The predicted results indoi:10.1155/2018/2943406 fatcat:srschwzodzbahmodvjg5nlb73m
