Measurement of angular parameters from the decay B0 → K⁎0μ+μ− in proton–proton collisions at s=8TeV
Angular distributions of the decay B0 → K∗0μ+μ− are studied using a sample of proton–proton collisions at √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 P1 and P� 5 parameters, where...

| Summary: | Angular distributions of the decay B0 → K∗0μ+μ− are studied using a sample of proton–proton collisions
at √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 P1 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 P1 and P�
5 parameters
are determined as a function of the dimuon invariant mass squared. The measurements are in agreement
with predictions based on the standard model |
