Single neutral heavy lepton production at electron–muon colliders

New heavy Majorana and Dirac neutrinos production at future electron–muon colliders are investigated. The production of a single heavy neutrino is shown to be more relevant than pair production when comparing cross sections and neutrino mass ranges. The process e ±μ ∓→ν ℓ ± W ∓ is studied including...

Description
Summary:New heavy Majorana and Dirac neutrinos production at future electron–muon colliders are investigated. The production of a single heavy neutrino is shown to be more relevant than pair production when comparing cross sections and neutrino mass ranges. The process e ±μ ∓→ν ℓ ± W ∓ is studied including on-shell and off-shell heavy neutrino effects. Distributions are calculated including hadronization effects and experimental cuts that suppress background, in order to have a clear signal for heavy neutral leptons.
