Analysis of high mass lepton flavour violating processes with CMS — •Aaron Hornschild, Sören Erdweg, Thomas Hebbeker, Arnd Meyer, and Swagata Mukherjee — III. Physikalisches Institut A, RWTH Aachen University
Lepton flavour violating processes are common in several models of physics beyond the Standard Model. Some models predict objects at the TeV mass scale that can decay into two standard model leptons of different flavour: electron + muon, muon + tau, or electron + tau.
The challenges in a search for such phenomena are to achieve a high mass resolution, good rejection of standard model backgrounds, and an efficient lepton identification at the same time.
The selection part of the analysis is presented, which is based on the 2016 CMS dataset corresponding to an integrated luminosity of 36 fb−1 at a center of mass energy of 13 TeV.
