MAJOR 1.5 — A Monte Carlo generator for heavy Majorana neutrinos in ep collisions Original Research Article

The Monte Carlo generator Major simulates the production and decay of heavy Majorana neutrinos via lepton mixing or exchange of ‘light’ right-handed W-bosons in deep inelastic scattering, i.e. e±p → NX → e±W±X or νeZX. Physics and programming aspects are described in this manual.
