Abstract
The B0s → μ+μ− is a flavor changing neutral current process highly suppressed at Standard Model (SM) tree level but it can still occur by loops. Particles expected in beyond SM theory can give contributions which change the SM Branching Ratio (BRSM = 3.23 ± 0.27 × 10−9 (Buras A. J., Acta Phys. Pol. B, 41(2010) 2487)). The current value of the Upper Limit (UL) set by ATLAS Collaboration with an integrated luminosity of 2.4 fb−1 collected at 7TeV is BR < 2.2×10−8 at 95% CL. In this study we present two improvements on UL procedure: SWAP technique and Unbinned Likelihood.
