Measurement of angular parameters from the decay B0→K∗0μ+μ−in proton–proton collisions at √s=8TeV. Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 781, 517-541. doi:10.1016/j.physletb.2018.04.030 | Abstract: | Angular distributions of the decay B0→K⁎0μ+μ− are studied using a sample of proton–proton collisions at s=8TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5fb−1. An angular analysis is performed to determine the P1 and P5 ′ parameters, where the P5 ′ 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 P5 ′ parameters are determined as a function of the dimuon invariant mass squared. The measurements are in agreement with predictions based on the standard model. | URI: | https://doi.org/10.1016/j.physletb.2018.04.030 https://hdl.handle.net/11147/7716 |
