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...
