Abstract

This analysis uses the CMS open data to study the angular distribution of high-mass dimuon pairs produced during proton-proton interaction at a center of mass energy of 8 TeV. The study uses the cosθCS\theta_{\text{CS}} variable defined in the Collins Soper frame. In the Standard Model, the production of high-mass dimuon pairs is dominated by the Drell-Yan process, which exhibits a strong forward-backward asymmetry. However, many scenarios beyond the Standard Model predict different shapes for the cosθCS\theta_{CS} distribution. In excess events beyond the Standard Model, the angular distribution can be used to distinguish between those models. The Mono-Z^{\prime} model has been used to interpret the data, and no deviation from the SM has been observed.
