Model Unspecific Search in CMS (MUSiC) - Results — •Lorenzo Vigilante, Arnd Meyer, Saranya Samik Ghosh, and Thomas Hebbeker — III. Physikalisches Institut A, RWTH Aachen, 52074 Aachen, Germany

The CMS experiment has been collecting data during proton-proton collisions at a center of mass energy of 13 TeV during Run 2 of the CERN LHC. This presents a unique opportunity to search for new physics phenomena beyond the Standard Model. The majority of searches for new physics are optimized for an established signal hypothesis in one or few decay channels. These searches cover only a fraction of all observed final states with model dependent analysis strategies. The Model Unspecific Search in CMS (MUSiC) provides a unique procedure to search for new physics at CMS in several hundred final states that are not all covered by dedicated analyses. This talk extends the previous introductory talk and presents the results of the MUSiC analysis using 35.9 fb⁻¹ of data recorded by the CMS detector at the LHC during proton-proton collisions at a center of mass energy of 13 TeV. The overall agreement between the CMS data and simulation of the Standard Model is evaluated and most significant deviations are studied.
