Search for new physics in the electron plus missing transverse momentum channel using Run-3 CMS data — Thomas Hebbeker, Kerstin Hoepfner, •Mirac Noyan Özdemir, Valentina Sarkisovi, Alexander Schmidt, and Karl Joseph Schumacher — III. Physikalisches Institut A, RWTH Aachen University

There are many Beyond the Standard Model (BSM) theories that predict new particles in the final state with a high-energy lepton and missing transverse momentum as their experimental signature. Now, using the newly acquired data of the CMS detector from the ongoing Run-3 at an unprecedented center-of-mass energy of 13.6 TeV, a new window is opened for searches in the high-energy regions.

This talk presents the main ideas behind the search for high-mass resonances and the analysis strategy in the electron plus missing transverse momentum channel. Among other results, the comparison of the observed data to the expected background, including a data-driven background estimation method, and several theoretical interpretations, will be shown.
