In this work we assess the potential of discovering new physics by searching for lepton-
flavour-violating (LFV) decays of the Z boson, Z → ℓ _i ℓ _j Z→ ℓ i ℓ j, at the proposed circular …

A bstract We analyse the effects of Dirac and Majorana neutrinos on leptonic decays of
muon and tau leptons using the most general four-lepton effective interaction Hamiltonian of …

We propose a minimal model where a dark sector, odd under a Z 2 discrete symmetry, is the
seed of lepton number violation in the neutrino sector at the loop level, in the context of the …

The lepton flavor violating (LFV) decays h, Z→ ebea, and eb→ ea γ are discussed in a class
of general 3-3-1 models adding heavy neutral leptons and singly charged Higgs bosons to …

Heavy neutral leptons are motivated by several extensions of the Standard Model and their
presence induces modifications in the lepton mixing matrix, including new Dirac and …

A bstract We study lepton flavor violation (LFV) within the Littlest Higgs Model with T parity
(LHT) realizing an inverse seesaw (ISS) mechanism of type I. With respect to the traditional …

The lepton flavor violating decays h→ eb±ea∓, Z→ eb±ea∓, and eb→ ea γ will be
discussed in the framework of the Two Higgs doublet model with presence of new inverse …

We propose a singlet majoron model that defines an inverse seesaw mechanism in the ν
sector. The majoron ϕ has a mass m ϕ≈ 0.5 eV and a coupling to the τ lepton similar to the …

A bstract We study the phenomenology of the minimal (2, 2) inverse-seesaw model
supplemented with Abelian flavour symmetries. To ensure maximal predictability, we …

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 …
