# Natural suppression of symmetry violation in gauge theories: Muon- and electron-lepton-number nonconservation

@article{Lee1977NaturalSO, title={Natural suppression of symmetry violation in gauge theories: Muon- and electron-lepton-number nonconservation}, author={B. Lee and R. Shrock}, journal={Physical Review D}, year={1977}, volume={16}, pages={1444-1473} }

We analyze the circumstances under which the violations of an approximate symmetry in a unified gauge theory of weak interactions are naturally suppressed; in particular, we investigate approximate muon- and electron-type lepton-number conservation as an example of such a symmetry. Extending earlier work, we propose a unified treatment of this symmetry together with strangeness conservation by the weak neutral current and $\mathrm{CP}$ invariance. The rate for the decay $\ensuremath{\mu… CONTINUE READING
