Charged lepton flavour-violating transitions would be a clear signal of new physics beyond
the Standard Model. Their search has been carried out in a variety of channels, the most …

Sterile neutrinos are among the most attractive extensions of the SM to generate the light
neutrino masses observed in neutrino oscillation experiments. When the sterile neutrinos …

The discovery of a non-zero rate for a lepton flavor violating decay mode of the Higgs boson
would definitely be an indication of New Physics. We review the prospects for such signal in …

Several experiments reported hints for the violation of lepton flavor or lepton flavor
universality in processes involving muons. Most prominently, there is the hint for a nonzero …

We explore the parameter space of lepton flavor violating (LFV) neutral Higgs Yukawa
couplings with the muon and tau leptons that can be probed at the high-luminosity Large …

A bstract We study the general Zee model, which includes an extra Higgs scalar doublet and
a new singly-charged scalar singlet. Neutrino masses are generated at one-loop level, and …

New physics in the lepton sector may account for neutrino masses, affect electroweak
precision observables, induce charged-lepton flavor violation, and shift dipole moments. The …

We explore the discovery prospect of a very heavy neutrino at the proposed e+ e-collider for
two different cm energies s= 1.4 and 3 TeV. We consider production of a heavy neutrino via …

A bstract We study lepton violating Higgs (HLFV) decays, first from the effective field theory
(EFT) point of view, and then analysing the different high-energy realizations of the …

Many new physics scenarios beyond standard model often necessitate the existence of a
(light) neutral scalar H, which might couple to the charged leptons in a flavor violating way …
