Abstract:
Using data collected by the FOCUS experiment at Fermilab, we present a new measurement of the charm semileptonic branching ratio \rhobr. From a sample of $320\pm44$ and $11373\pm161$ \rhomunu ~and \kpimunu ~events respectively, we find $\rhobr=0.041\pm0.006~\textrm{(stat)}\pm0.004~\textrm{(syst)}$.
