Multiple theories beyond the Standard Model predict the existence of heavy neutrinos in order to explain the light neutrino masses, such as the Type I seesaw mechanism, which introduces new heavy neutrino states without additional vector bosons, or the Type III seesaw mechanism which introduces additional heavy lepton triplets. Left-right symmetric models, which restore parity symmetry in weak...
The talk will present a review of the most recent results obtained by the ATLAS and CMS experiments at the CERN LHC on the searches for New Physics using multi-lepton final states.
At the energies of the Large Hardon Collider vector bosons, higgs bosons and top quarks are often produced with momenta significantly higher than their rest mass. This means that if they decay hadronically their decay products boosted such that they fall in a small area in eta-phi. The identification of these interesting objects over the large backgrounds of jets from QCD processes poses an...
