Abstract:We study the exclusive semileptonic rare B + c → D + νν decay in the framework of light-cone quark model. The transition form factors f + (q 2 ) and f T (q 2 ) are evaluated in the time-like 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 B + c → D + νν decay is calculated and compared with the other theoretical model predictions. The predicted result… Show more
