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

The standard model of particle physics is increasingly challenged by recent discoveries and also by long known phenomena, representing a strong motivation to develop extensions of the standard model. The amount of theories describing possible extensions is large and steadily growing.

In this presentation a new approach is introduced, verifying if a given theory beyond the standard model is consistent with data collected by the CMS detector without the need to perform a dedicated search. To achieve this, model unspecific limits on the number of additional events above the standard model expectation are calculated in every event class produced by the MUSiC algorithm. Furthermore, a tool is provided to translate these results into limits on the signal cross section of any theory.

In addition to the general procedure, first results and examples are shown using the proton-proton collision data taken at a centre of mass energy of 8 TeV.
