Analysis of high mass lepton flavour violating processes with CMS — •Aaron Hornschild, Thomas Hebbeker, Sören Erdweg, 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 scale that can decay into two charged standard model leptons of different flavour, like electron + muon or muon + tau. For example supersymmetry with R-parity violation can permit resonant sneutrino production which could decay into such two different leptons. This scenario results in an excess of events at high invariant masses, thus leading to a striking signature with low standard model background.

In this talk the analysis of such a lepton flavour violating process is presented, based on the 2016 CMS dataset corresponding to an integrated luminosity of 36 fb⁻¹ at a pp center of mass energy of 13 TeV.
