Model Unspecific Search in CMS - Treatment of Insufficient Monte Carlo Statistics — •Jonas Lieb, Andreas Albert, Deborah Duchardt, Thomas Hebbeker, Simon Knutzen, Arnd Meyer, Tobias Pook, and Jonas Roemer — III. Physikalisches Institut A, RWTH Aachen University

In 2015, the CMS detector recorded proton-proton collisions at an unprecedented center of mass energy of √s = 13 TeV. The Model Unspecific Search in CMS (MUSiC) offers an analysis approach of these data which is complementary to dedicated analyses: By taking all produced final states into consideration, MUSiC is sensitive to indicators of new physics appearing in final states that are usually not investigated.

In a two step process, MUSiC first classifies events according to their physics content and then searches kinematic distributions for the most significant deviations between Monte Carlo simulations and observed data.

Such a general approach introduces its own set of challenges. One of them is the treatment of situations with insufficient Monte Carlo statistics.

Complementing introductory presentations on the MUSiC event selection and classification, this talk will present a method of dealing with the issue of low Monte Carlo statistics.
