The B^0_s -> eta_c(4h) phi(K+K-) reconstruction at LHCb

We present the results of the B_s -> eta_c(4h) phi(K+K-) reconstruction at LHCb, based on a full Monte Carlo simulation. The expected untagged annual signal yield is of (3.2 +/-0.4)k events. The dominant background contribution is assumed to come from b bbar events such that the estimated backgro...

Sumario:We present the results of the B_s -> eta_c(4h) phi(K+K-) reconstruction at LHCb, based on a full Monte Carlo simulation. The expected untagged annual signal yield is of (3.2 +/-0.4)k events. The dominant background contribution is assumed to come from b bbar events such that the estimated background level is B/S < 1.4 at 90% confidence level.
