Abstract We calculate the ratios R τ/P ≡ Γ (τ → Pν τ [γ]) /Γ (P → μν μ [γ]) (P = π, K) at one loop following a large-N C expansion where Chiral Perturbation Theory is enlarged by including the lightest resonances and respecting the

Abstract We have revisited the computations of the flavor violating leptonic decays of the $$\tau $$ τ and $$\mu $$ μ leptons into three lighter charged leptons in the Standard Model with massive neutrinos. We were driven by a claimed unnaturally l

Abstract We obtain analytical expressions, both in terms of parametric integrals and Passarino–Veltman scalar functions, for the one-loop contributions to the anomalous weak magnetic dipole moment (AWMDM) of a charged lepton in the framework of the

In the first paragraph of section 4, the sentence “Without loss of generality, we assume the CP-conserving scenario” is incorrect.

Higgs-flavon fields appear as a part of the Froggatt–Nielsen (FN) mechanism, which attempts to explain the hierarchy of Yukawa couplings. We explore the possibility that the 750 GeV diphoton resonance recently reported at the LHC13 could be identif

The presence of massive sterile neutrinos $N$ mixed with the active ones induces flavor violating processes in the charged lepton sector at the loop level. In particular, the amplitude of ${H}^{0}\ensuremath{\rightarrow}{\overline{\ensuremath{\ell}}}
