Decay L0-->νlγ in gauge theories of weak and electromagnetic interactions
Abstract
Results are presented of a calculation of the rate for the decay L0-->νlγ, where L0=E0, M0 is a neutral heavy lepton occurring in certain gauge theories of weak and electromagnetic interactions. This rate is compared with that for the semileptonic decay mode L0-->l-π+, and it is found that, although the former is of order α3, whereas the latter is of order α2, the L0-->νlγ rate can actually exceed the L0-->l-π+ rate in models which also have a charged heavy lepton L+.
