Angular analysis of the decay B0→K*0μ+μ- from pp collisions at s=8 TeV. Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 753, 424-448. doi:10.1016/j.physletb.2015.12.020 | Abstract: | The angular distributions and the differential branching fraction of the decay B0→K⁎(892)0μ+μ− are studied using data corresponding to an integrated luminosity of 20.5 fb−1 collected with the CMS detector at the LHC in pp collisions at s=8 TeV. From 1430 signal decays, the forward–backward asymmetry of the muons, the K⁎(892)0 longitudinal polarization fraction, and the differential branching fraction are determined as a function of the dimuon invariant mass squared. The measurements are among the most precise to date and are in good agreement with standard model predictions. © 2015 CERN for the benefit of the CMS Collaboration | URI: | https://doi.org/10.1016/j.physletb.2015.12.020 | ISSN: | 0370-2693 |
