Abstract

We describe a method that provides a model independent measurement of the B_S fraction in \ensuremathΥ(5S) resonance decays, f_S, using the relative rates of like-sign versus opposite-sign dileptons; the like-sign leptons result from B⁰ and B_S mixing. In addition, we show that determining the rates of single, double and triple D_S^\ifmmode±\else\textpm\fi mesons provides an alternative way of finding f_S.
