$τ^{-} \to π^{-} η ν_{τ}$ decay induced by QED one-loop effects

Gerardo Hernández-Tomé, Gabriel López Castro, Diego Portillo-Sánchez

The $τ^{-} \to π^{-} η ν_{τ}$ decay is forbidden in the Standard Model in the limit of exact $G$ -parity, it becomes a rare decay due to isospin symmetry breaking and it is very sensitive t…

Dirac-Majorana neutrinos distinction in four-body decays

Juan Manuel Márquez, Diego Portillo-Sánchez, Pablo Roig

A novel method to differentiate the effects of Dirac and Majorana (D-M) neutrinos in four-body decays has been discussed in arXiv:2106.11785. There, it is concluded that the back-t…

Resonant Majorana neutrino effects in $Δ$ L=2 four-body hyperon decays

Gerardo Hernández-Tomé, Diego Portillo-Sánchez, Genaro Toledo

We computed the $Σ^{-} \to n π^{+} e^{-} ℓ^{-}$ ( $ℓ = e, μ$ ), $Ξ^{-} \to Λ π^{+} e^{-} e^{-}$ , and $Λ \to p π^{+} e^{-} e^{-}$ lepton number violating (LNV) hyperon decays mediated by a resonant Majorana neutr…

$Δ$ L=2 hyperon decays induced by Majorana neutrinos and doubly-charged scalars

G. Hernández-Tomé, G. López Castro, D. Portillo-Sánchez

Searches for $Δ L = 2$ decays are crucial to disentangle the Dirac vs Majorana nature of neutrinos. While neutrinoless nuclear double beta decays are the most promising tool to look f…
