Title: Measurement of angular parameters from the decay $$\mathrm{B}^0 \to \mathrm{K}^{*0} \mu^+ \mu^-$$ in proton-proton collisions at $$\sqrt{s} = $$ 8 TeV

Abstract

Angular distributions of the decay $$\mathrm{B}^0 \to \mathrm{K}^{*0} \mu^ +\mu^-$$ are studied using a sample of proton-proton collisions at $$\sqrt{s} = $$ 8 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5 fb$$^{-1}$$. An angular analysis is performed to determine the $$P_1$$ and $$P_5'$$ parameters, where the $$P_5'$$ parameter is of particular interest because of recent measurements that indicate a potential discrepancy with the standard model predictions. Based on a sample of 1397 signal events, the $$P_1$$ and $$P_5'$$ parameters are determined as a function of the dimuon invariant mass squared. The measurements are in agreement with predictions based on the standard model.
