LHC sensitivity to singly-charged scalars decaying into electrons and muons
Julien Alcaide, Nicolás I. Mileo
Current LHC searches for non-supersymmetric singly-charged scalars, based on Two-Higgs-Doublet models, in general focus the analysis on third-generation fermions in the final state…
Probes of the Standard Model effective field theory extended with a right-handed neutrino
Julien Alcaide, Shankha Banerjee, Mikael Chala +1
If neutrinos are Dirac particles and, as suggested by the so far null LHC results, any new physics lies at energies well above the electroweak scale, the Standard Model effective f…
Fitting flavour symmetries: the case of two-zero neutrino mass textures
Julien Alcaide, Jordi Salvado, Arcadi Santamaria
We present a numeric method for the analysis of the fermion mass matrices predicted in flavour models. The method does not require any previous algebraic work, it offers a …
LHC signals of radiatively-induced neutrino masses and implications for the Zee-Babu model
Julien Alcaide, Mikael Chala, Arcadi Santamaria
Contrary to the see-saw models, extended Higgs sectors leading to radiatively-induced neutrino masses do require the extra particles to be at the TeV scale. However, these new stat…
A model of neutrino mass and dark matter with large neutrinoless double beta decay
Julien Alcaide, Dipankar Das, Arcadi Santamaria
We propose a model where neutrino masses are generated at three loop order but neutrinoless double beta decay occurs at one loop. Thus we can have large neutrinoless double beta de…
