Selection of the decay B_s^0->phi\mu^+\mu^- at LHCb

An offline selection of the rare semileptonic decay B_s^0->phi mu^+mu^- is presented. The events are triggered and selected with an efficiency of epsilon_tot=(0.84+-0.02 )%. For a nominal year of LHCb data taking (2 fb^-1) the signal yield is expected to be 1340+-250 events and the background-to-...

Sumario:An offline selection of the rare semileptonic decay B_s^0->phi mu^+mu^- is presented. The events are triggered and selected with an efficiency of epsilon_tot=(0.84+-0.02 )%. For a nominal year of LHCb data taking (2 fb^-1) the signal yield is expected to be 1340+-250 events and the background-to-signal ratio B/S<0.7 at 90% C.L. The background has been studied using inclusive b~b and specific b->mu^-X, ~b->mu^+X samples.
