Angular distributions of the decay B0 → K∗0μ+μ- are studied using data corresponding to an integrated luminosity of 20.5 fb-1 collected with the CMS detector at the LHC in proton-proton collisions at √s = 8 TeV. An angular analysis is performed, providing results for a number of physical observables, including P5, which is of particular interest due to measurements from the LHCb Collaboration that exhibit potential discrepancy with the standard model. Based on a sample of 1397 signal events, the P1 and P5' angular parameters are determined as a function of the dimuon invariant mass squared. The measurement are in agreement with standard model predictions.

Abstract
Angular distributions of the decay B0 → K∗0μ+μ- are studied using data corresponding to an integrated luminosity of 20.5 fb-1 collected with the CMS detector at the LHC in proton-proton collisions at √s = 8 TeV. An angular analysis is performed, providing results for a number of physical observables, including P5, which is of particular interest due to measurements from the LHCb Collaboration that exhibit potential discrepancy with the standard model. Based on a sample of 1397 signal events, the P1 and P5' angular parameters are determined as a function of the dimuon invariant mass squared. The measurement are in agreement with standard model predictions.
