  Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton
collision data recorded at the LHC at a centre-of-mass energy of 13 TeV,
corresponding to an integrated luminosity of 35.9 fb$^{-1}$, are presented. The
MUSiC analysis searches for anomalies that could be signatures of physics
beyond the standard model. The analysis is based on the comparison of observed
data with the standard model prediction, as determined from simulation, in
several hundred final states and multiple kinematic distributions. Events
containing at least one electron or muon are classified based on their final
state topology, and an automated search algorithm surveys the observed data for
deviations from the prediction. The sensitivity of the search is validated
using multiple methods. No significant deviations from the predictions have
been observed. For a wide range of final state topologies, agreement is found
between the data and the standard model simulation. This analysis complements
dedicated search analyses by significantly expanding the range of final states
covered using a model independent approach with the largest data set to date to
probe phase space regions beyond the reach of previous general searches.
