Abstract: Results of the Model Unspecific Search in CMS (MUSiC) using data recorded by the CMS detector at the LHC, during proton-proton collisions at a center of mass energy of $\sqrt{s}= $ 13 TeV in 2016 and corresponding to an integrated luminosity of 35.9 fb$^{-1}$, are presented. The MUSiC analysis aims to search for anomalies that could be probed as signatures for phenomena beyond the standard model, and is based on the comparison of data with the expectation according to the standard model, determined from simulations, in several hundred final states and multiple kinematic distributions. Events containing at least one lepton are classified based on their final state topology, and an automated search algorithm subsequently surveys the data for deviations from the expectation. The sensitivity of the search is validated using multiple methods. No significant deviations beyond the expectations have been found. For a wide range of final state topologies, good agreement is found between the data and simulation of the standard model.
