The mediators of neutrino mass generation can provide valuable information about neutrino properties, such as mass scale, mass-ordering, and atmospheric octant. Studying the decays of Higgs triplet scalars can shed light on these aspects. Four-lepton signatures at high-energy colliders could be a potential discovery site for charged lepton flavor non-conservation.
The mediators of neutrino mass generation can provide a probe of neutrino properties at the next round of high-energy hadron (FCC-hh) and lepton colliders (FCC-ee/ILC/CEPC/CLIC). We show how the decays of the Higgs triplet scalars mediating the simplest seesaw mechanism can shed light on the neutrino mass scale and mass-ordering, as well as the atmospheric octant. Four-lepton signatures at the high-energy frontier may provide the discovery-site for charged lepton flavor non-conservation in nature, rather than low-energy intensity frontier experiments.
