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


Abstract

Angular distributions of the decay $B^0 \to K^{*0} \mu^+ \mu^-$ 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 and parameters are determined as a function of the dimuon invariant mass squared. The measurements are in agreement with predictions based on the standard model.
