Model Unspecific Search in CMS - Results at 8 TeV — •Andreas Albert, Deborah Duchardt, Thomas Hebbeker, Simon Knutzen, Jonas Lieb, Arnd Meyer, Tobias Pook, and Jonas Roemer — III. Physikalisches Institut A, RWTH Aachen University

In the year 2012, CMS collected a total data set of approximately 20 fb⁻¹ in proton-proton collisions at √s=8 TeV.

Dedicated searches for physics beyond the standard model are commonly designed with the signatures of a given theoretical model in mind. While this approach allows for an optimised sensitivity to the sought-after signal, it may cause unexpected phenomena to be overlooked.

In a complementary approach, the Model Unspecific Search in CMS (MUSiC) analyses CMS data in a general way. Depending on the reconstructed final state objects (e.g. electrons), collision events are sorted into classes. In each of the classes, the distributions of selected kinematic variables are compared to standard model simulation. An automated statistical analysis is performed to quantify the agreement between data and prediction.

In this talk, the analysis concept is introduced and selected results of the analysis of the 2012 CMS data set are presented.
