Novel Technique for Low-Mass Type I Heavy Majorana Neutrino Searches

With the absence of new physics in searches at higher masses at the LHC, there is an increased emphasis on investigating lower mass regimes. We propose a new technique specifically designed to explore particles with masses below 200 GeV, particularly those produced in association with a high-pT lepton and exhibiting Lorentz boosting. We apply this approach to the search for Type I heavy Majorana neutrinos and compare our results with other techniques employed to investigate this phase space.
