18. Even for quasidegenerate heavy Majorana neutrinos (as occurs in specific models), the LNV signal can be sizable when the mass splitting Δ M N ≡ M N 1-M N 2 is comparable to the width Γ N ≡ (Γ N 1 + Γ N 2) / 2 [13]. For instance, for the on-shell production of N 1, 2 with average four-momentum squared s ̄ = (M N 1 2 + M N 2 2) / 2, the LNV amplitude in the muon-channel is given by A LNV μ μ (s ̄) =-V μ N 1 2 (2 Δ M N / Δ M N 2 + Γ N 2) + O (Δ M N / M N 1), for Δ M N â‰ Γ N.
