A large number of theories beyond the standard model predict new phenomena observable at the LHC. Many of those theories are tested by dedicated analyses at CMS and the other LHC experiments. However, new physics could as well manifest itself in ways nobody has thought of yet. Thus we have implemented a Model Unspecific Search in CMS: “MUSiC”. MUSiC automatically scans and compares the measured data to the simulated standard model expectations without assumptions on specific models of new physics. Thus covering a large phase space, it is sensitive to a lot of potential signals.

This analysis pushes the limits of feasability in different ways. It is not only computationally demanding, but also challenges our understanding of detector simulation, Monte Carlo generators, and statistical interpretation.
