Abstract
We report the first observation of the Cabibbo disfavored semileptonic decay mode D+ --> rho(770)0mu+nu and measure its decay rate relative to the Cabibbo favored mode D+ --> KBAR (892)0mu+nu to be GAMMA(D+ -- > rho(770)0mu+nu/GAMMA(D+ --> KBAR(892)0mu+nu = 0.044(+0.031/-0.025) (stat.) +/- 0.014 (syst.). The results are compared to theoretical pre dictions and to previous experimental upper limits.
