Abstract
This analysis uses the Compact Muon Solenoid (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 variable defined in the Collins-Soper frame. In the Standard Model (SM), 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 SM predict different shapes for the cosθCS distribution. In excess events beyond the SM, 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.
