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 cos 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 cos distribution. In excess events beyond the Standard Model, the angular distribution can be used to distinguish between those models. The Mono-Z model has been used to interpret the data, and no deviation from the SM has been observed.
