$$\tau \rightarrow \mu \mu \mu $$ τ→μμμ at a rate of one out of $$10^{14}$$ 1014 tau decays?
Abstract We present in a full analytic form the partial widths for the lepton flavour violating decays $$\mu ^{\pm } \rightarrow e^{\pm } e^+ e^-$$ μ±→e±e+e- and $$\tau ^{\pm } \rightarrow \ell ^{\pm } \ell '^{+} \ell '^{-}$$ τ±→ℓ±ℓ′+ℓ′- , with $$\ell ,\ell '=\mu ,e$$ ℓ,ℓ′=μ,e , media...
