Model Unspecific Search in CMS - First Results at 13 TeV — •Jonas Roemer, Andreas Albert, Deborah Duchardt, Thomas Hebbeker, Simon Knutzen, Jonas Lieb, Arnd Meyer, and Tobias Pook — III. Physikalisches Institut A, RWTH Aachen University

Following an upgrade in center of mass energy from √s = 8 TeV to 13 TeV, the LHC delivered first proton-proton collisions at this unprecedented energy in 2015. The CMS experiment recorded data corresponding to an integrated luminosity of 3.7 fb⁻¹. Since many theoretical models predict signal cross sections to increase strongly with the center of mass energy, the data taken at √s = 13 TeV are competitive to the previous data taking period even with a lower recorded integrated luminosity.

The Model Unspecific Search in CMS (MUSiC) searches for physics beyond the standard model independent of theoretical models. Using an automatic method, kinematic distributions of the data are compared with the standard model expectation in every final state. Therefore, MUSiC reduces the chance of overlooking new physics, since even distributions not covered by dedicated analyses are investigated.

This talk outlines changes to the analysis made necessary by the increased center of mass energy and first results with lepton triggered events.
