MUSiC: A Model Unspecific Search for New Physics — •Deborah Duchardt1 and Thomas Hebbeker2 — 1Berlin — 2III. Physikalisches Institut A, RWTH Aachen
The Large Hadron Collider (LHC), currently the highest energy proton-proton collider and at the forefront of today’s particle physics research, is an ideal setting for seeking out signatures of new physics. At the LHC’s Compact Muon Solenoid (CMS) experiment dedicated searches are conducted in anticipation of revealing signs of specific theory models beyond the established Standard Model of particle physics. In doing so, some classes of collision events are left unconsidered, e.g. ones with complex final states. However, signatures of new, unthought-of theories may be hidden even there.
Therefore, the "Model Unspecific Search in CMS" (MUSiC) follows an unbiased approach, exempting dedicated theory model assumptions and specific kinematic selections. Instead, the search is carried out in several hundreds of final states. An automated statistical analysis quantifies the significance of deviations observed between the data and a Monte-Carlo simulated prediction of the Standard Model.
In this talk general concepts of the MUSiC analysis and new methods developed for my thesis will be discussed. Moreover, search results based on 8 TeV CMS data will be summarized, which show a very good agreement between data and Standard Model expectation. This analysis was also published as CMS-PAS-EXO-14-016.
