We describe a method that provides a model independent measurement of the BS fraction in Υ(5S) resonance decays, fS, using the relative rates of like-sign versus opposite-sign dileptons; the like-sign leptons result from B0 and BS mixing. In addition, we show that determining the rates of single, double and triple DS± mesons provides an alternative way of finding fS.
