Abstract: (Elsevier)
A clear signal for the existence of new physics beyond M w would be the non-conservation of either the separate lepton numbers L e , L μ , L τ , of total lepton number L , or of baryon number B . At low energy these violations are described by an effective theory containing only the known quarks and leptons with vertices of dimension five or higher that are SU(3)×SU(2)×U(1) invariant. We systematically catalogue the relations imposed by this invariance on the numerous processes which might violate L e , L μ , L τ , L τ , or B. Processes considered include μ →e γ , ν μ N→ ν e N, ν μ e − → ν e μ − , τ − →e + μ − μ − , ν μ p→ μ + n, p→e − K + γ + , p→e + γ , n ↔ n p→ π + + 3 ν , p →μ + e + π − ν , p→ μ + μ + e − , n→ μ + e − ν . Some of these processes are found to be suppressed.- LEPTON NUMBER: VIOLATION
