MUSiC, a Model Unspecific Search for New Physics, in pp Collisions at $\sqrt{s}=8\,\mathrm{TeV}$

This analysis summary presents the results of the Model Unspecific Search in CMS (MUSiC) based on data taken by the CMS detector at the LHC at a proton-proton center of mass energy of $\sqrt{s}=8\,\mathrm{TeV}$. Based on comparisons to standard model (SM) simulations, this search for unexpected new physics covers a wide array of final states with minimal theoretical bias. Events collected with electron and muon triggers are sorted into classes based on their final state topology, taking electrons, muons, photons, jets and missing transverse energy into account. For the analyzed data corresponding to about $20\,\mathrm{fb}^{-1}$, this results in more than 200 event classes. The automated search algorithm subsequently surveys kinematic distributions of the data for deviations from the SM expectations, calculating a statistical significance. The sensitivity of the analysis is validated by surveying simulations of hypothetical models and by omitting known SM processes from the simulation. No indication of new physics has been found in the analyzed data. For a wide range of final state topologies, good agreement is found between the data and Monte Carlo based SM simulation.
