A search for Beyond the Standard Model physics is performed with the ATLAS detector in the opposite sign dimuon channel using the 20 fb 1 of data collected in 2012 at √s = 8 TeV. No excess is found above the Standard Model expectation. Using a Bayesian statistical analysis, mode…

The impressive progress that elementary particle physics made in the second half of the last century led to the formulation of a comprehensive theory, known as the Standard Model (SM), which correctly describes all fundamental interactions in nature, except for the gravitational…
