$τ$ data-driven evaluation of Euclidean windows for the hadronic vacuum polarization

Pere Masjuan, Alejandro Miranda, Pablo Roig

We compute for the first time the $τ$ data-driven Euclidean windows for the hadronic vacuum polarization contribution to the muon $g - 2$ . We show that $τ$ -based results agree with 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…

Lepton Flavor Violation from diphoton effective interactions

Fabiola Fortuna, Xabier Marcano, Marcela Marín +1

We consider charged lepton flavor violating transitions mediated by the diphoton effective interactions $ℓ_{i} ℓ_{j} γ γ$ and explore which processes can probe them better. Our anal…

Radiative corrections to the $τ^{-} \to (P_{1} P_{2})^{-} ν_{τ}$ ( $P_{1, 2} = π, K$ ) decays

Rafel Escribano, Alejandro Miranda, Pablo Roig

The radiative corrections to the $τ^{-} \to (P_{1} P_{2})^{-} ν_{τ}$ ( $P_{1, 2} = π, K$ ) decays are calculated for the first time including the structure-dependent real photon corrections, which a…

Tension between $e^{+} e^{-} \to η π^{-} π^{+}$ and $τ^{-} \to η π^{-} π^{0} ν_{τ}$ data and non-standard interactions

Saray Arteaga, Ling-Yun Dai, Adolfo Guevara +1

We show the discrepancy between the isospin-rotated $e^{+} e^{-} \to η π^{-} π^{+}$ cross-section -- measured by various collaborations -- and the Belle $τ^{-} \to η π^{-} π^{0} ν_{τ}$ spectrum, which canno…

Indirect upper limits on $ℓ_{i} \to ℓ_{j} γ γ$ from $ℓ_{i} \to ℓ_{j} γ$

Fabiola Fortuna, Alejandro Ibarra, Xabier Marcano +2

We perform an effective field theory analysis to correlate the charged lepton flavor violating processes $ℓ_{i} \to ℓ_{j} γ γ$ and $ℓ_{i} \to ℓ_{j} γ$ . Using the current upper bounds…
