The B_s0->J/psi(mu+ mu-)eta(gamma gamma) reconstruction at LHCb

We present a selection analysis of the "B_s0->J/psi eta" decay based on 50'000 Monte Carlo signal events and a study of the associated background which mostly originated from b-bbar events; the statistics used for this latter is 10'452'600 events. At the present stage of...

description We present a selection analysis of the "B_s0->J/psi eta" decay based on 50'000 Monte Carlo signal events and a study of the associated background which mostly originated from b-bbar events; the statistics used for this latter is 10'452'600 events. At the present stage of the software development, the signal yield is expected to be (7.0 +- 0.3)*10^3 per year and the background over signal ratio is expected to be in the range 0.57 to 6.3 at a 90% confidence level.
