Characterizing Heavy Neutral Leptons: Measuring Parameters, Discriminating Majorana versus Dirac, and Using FASER2 as a Trigger for ATLAS
Jonathan L. Feng, Alec Hewitt, Daniel La Rocco +1
This work explores the potential of the proposed FASER2 experiment at the LHC to determine the properties of a discovered heavy neutral lepton (HNL), including its mass, couplings,…

Simulating Heavy Neutral Leptons with General Couplings at Collider and Fixed Target Experiments
Jonathan L. Feng, Alec Hewitt, Felix Kling +1
Heavy neutral leptons (HNLs) are motivated by attempts to explain neutrino masses and dark matter. If their masses are in the MeV to several GeV range, HNLs are light enough to be…
