Sumario:The Model Unspecific Search in CMS (MUSiC) is an approach to analyse the data taken with the CMS detector at the Large Hadron Collider at CERN. This thesis uses the MUSiC code developed for the analysis of the measurements performed at a centre of mass energy of 13 TeV. In contrast to dedicated analyses, MUSiC does not pursue a search strategy which is optimised for a certain theory prediction beyond the Standard Model of particle physics. One of the final outcomes of the MUSiC analysis is a global comparison between the deviations between measurement and Standard Model Monte Carlo simulations and the statistically expected deviations expected from the Standard Model only hypothesis, the p˜-distribution. The aim of this thesis is to conduct a sensitivity study by investigating the effects an injected signal instead of observed data has on the distribution. The examined signal samples originate from Monte Carlo simulations on the basis of an R-parity-violating Supersymmetry model with a specific choice of supersymmetrical couplings constants. The effects of scenarios with different tau-sneutrino masses are considered. It appears that MUSiC is principally sensitive to the model in question, but the extent of deviation depends strongly on the choice of tau-sneutrino masses as parameters. The achieved sensitivity is compared to the sensitivity of the dedicated analysis [9] with the result that the sensitivities of both approaches are similar for the considered model.
