Model Unspecific Search in CMS - Signal Studies — •Jonas Lieb, Deborah Duchardt, Thomas Hebbeker, Simon Knutzen, Arnd Meyer, Tobias Pook, and Jonas Roemer — III. Physikalisches Institut A, RWTH Aachen University

In 2015 and 2016, the CMS detector recorded proton-proton collisions at an unprecedented center of mass energy of √s = 13 TeV. The Model Unspecific Search in CMS (MUSiC) offers an analysis approach of these data which is complementary to dedicated analyses: By taking all produced final states into consideration, MUSiC is also sensitive to indicators of new physics appearing in final states that are usually not investigated.

In a two step process, MUSiC first classifies events according to their physics content and then searches kinematic distributions for the most significant deviations between Standard Model Monte Carlo simulations and observed data.

To assess MUSiC’s sensitivity, simulated signal events of new physics processes are mixed with Standard Model Monte Carlo background. The automated search is repeated on pseudo-data diced with this expectation and the analysis’ response is statistically analyzed.

Complementing introductory presentations on the MUSiC event selection and classification, this talk will show how new physics would show up in MUSiC results.
