| contents | 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$θ_{\text{CS}}$ 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 cos$θ_{CS}$ 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. |
