’t Hooft (1976) observed that the standard model does not absolutely conserve baryon and lepton number due to the Adler-Bell-Jackiw anomaly The process ‘t Hooft considered was spontaneous fermion number violation due to instanton induced transitions. Attracting much attention Ringwald (1990) recently argued, that such tunnelling transitions between topologically distinct vacua might indeed be observable at high energies at future accelerators (Mattis and Mottola, 1990).
