Extension of the Model Unspecific Search in CMS to Final States with Jets using 2012 Data

The Model Unspecific Search in CMS (MUSiC) is presented. In MUSiC, proton-proton collision events are sorted into event classes based on final state topology. For each event class, distributions of kinematic variables in data and Monte Carlo simulation of Standard Model physics are automatically compa...

description The Model Unspecific Search in CMS (MUSiC) is presented. In MUSiC, proton-proton collision events are sorted into event classes based on final state topology. For each event class, distributions of kinematic variables in data and Monte Carlo simulation of Standard Model physics are automatically compared. The search is explicitly not optimised for any specific model of New Physics to avoid missing phenomena in unexpected topologies. The analysis strategy is applied to the full data set collected at √s = 8 TeV by CMS in 2012 corresponding to an integrated luminosity of 19.5 fb−1. Special emphasis is placed on jet triggered events, which have not previously been considered in the MUSiC analysis. The results of the analysis are presented and discrepancies between data and simulation are studied. A simulation-based sensitivity study is performed to demonstrate the analysis performance for a potential Dark Matter phenomenom.
