Searches for new physics with MUSiC in pp collisions at √s=13 TeV in 2018 CMS Data — Thomas Hebbeker, •Yannik Kaiser, Lucas Karwatzki, Arnd Meyer, Chinmay Seth, and Felipe Torres da Silva de Araujo — III. Physikalisches Institut A, RWTH Aachen University

Despite the large effort of the LHC collaborations, no direct evidence for physics beyond the Standard Model has been found. Considering several theory models available, which address the inadequacies of the Standard Model, many model-specific searches have been employed. Complementary to this approach is MUSiC - Model Unspecific Search in CMS - a model-independent search procedure in which data collected by the CMS experiment are classified according to their final state multiplicities of well-reconstructed objects. For each class a search algorithm is applied to identify regions where the CMS measurements deviate from the theoretical prediction. The algorithm is based on a well-defined p-value and a complete simulation of the Standard Model. The procedure also takes into account systematic and statistical effects. As an extension of the already published result using 2016 data, we report preliminary results of the MUSiC search on data collected by CMS during 2018, corresponding to 58.83 fb⁻¹ of integrated luminosity.
