The forward direction of particle production in
proton-proton interactions at the Large Hadron Collider can serve as an
intense source of high energy neutrinos of all neutrino-flavours, that stem
from hadron decays. Two experiments located
at a distance of 480 m away from the ATLAS experiment, along the beam line
of sight, FASER(Nu) and SND@LHC, have been installed during the last LHC...
I will discuss a TeV-scale extension of the Standard Model in which a dark sector facilitates neutrino mass generation radiatively within the context of the linear seesaw mechanism. Since the symmetries of the model prevent tree-level contributions, tiny neutrino masses are generated at one loop due to spontaneous lepton number violation by the expectation value of a Higgs triplet. I will...
In this talk I will describe an extension of the Standard Model designed to elucidate the fermion mass hierarchy, account for the dark matter relic abundance, and explain the observed matter-antimatter asymmetry in the universe. Beyond the Standard Model particle content, the model introduces additional scalars and fermions. Notably, the light active neutrinos and the first two generations of...
We propose two versions of radiative linear seesaw models, where electrically charged scalars and vector-like leptons generate the Dirac neutrino mass submatrix at one and two loop levels. In these models, the SM charged lepton masses are generated from a one loop level radiative seesaw mechanism mediated by charged exotic vector-like leptons and electrically neutral scalars running in the...
