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.enCMSPhysicsB0decaysArticle10.1016/j.physletb.2018.04.0302-s2.0-85046377779Q1WOS:000435653100067Q2
