# 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 ⁎ are studied using a sample of proton–proton collisions at collected with the CMS detector at the LHC, corresponding to an integrated luminosity of . An angular analysis is performed to determine the and parameters, where the 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.
