Özet
Angular distributions of the decay B0?K?0?+??are studied using a sample of proton–proton collisions at ?s=8TeVcollected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5fb?1. An angular analysis is performed to determine the P1and P 5parameters, where the P 5parameter 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 P1and P 5parameters are determined as a function of the dimuon invariant mass squared. The measurements are in agreement with predictions based on the standard model.
