Resonant CP violation in rare τ ± decays
Abstract In this work, we study the lepton number violating tau decays via intermediate on-shell Majorana neutrinos N j into two scalar mesons and a lepton τ ± → M 1 ± N j → M 1 ± M 2 ± ℓ ∓. We calculate the Branching ratios Br(τ ±) and the CP asymmetry (Γ(τ +) − Γ(τ −))/(Γ(τ +) + Γ(τ −)) for such...
