Search for Heavy Majorana Neutrinos in same-sign W Boson Scattering — •Jonas Neundorf — Deutsches Elektronen-Synchrotron, Notkestraße 85, 22607 Hamburg

Among the open question of particle physics is the origin of neutrino masses. While they are predicted to be zero by the Standard Model, oscillation measurements have shown that at least two of the three neutrino flavours observed in nature are massive. These masses can be explained by the "Seesaw Mechanism", which introduces Majorana neutrinos with a mass on the TeV scale. For the first time at the LHC, a search for Heavy Majorana Neutrinos produced via same-sign W boson scattering is performed. This talk will discuss the discovery potential and outline the analysis design.
