Abstract

An angular analysis of the B⁰→K^*0 μ⁺μ⁻ decay is performed in pp collisions at √s = 7 TeV, with a data sample corresponding to an integrated luminosity of 5.2 fb⁻¹ collected by the CMS experiment at the LHC. The forward-backward asymmetry of the muons A_FB, the K^*0 longitudinal polarization fraction F_L, and the differential branching fraction dℬ/dq², are measured as function of the dimuon invariant mass squared, q². The results are in good agreement with the standard model expectations.
