We propose a new seesaw model based on fermionic hypercharge zero weak quintuplet in conjunction with additional scalar quadruplet which attains an induced vev. The model provides both tree-level seesaw ~ v^6/M^5 and a loop-suppressed radiative ~ (1 / 16 \pi^2) v^2/M contributions to active neutrino masses. The empirical masses m_\nu ~ 10^{-1} eV can be achieved with M ~ TeV new states, accessible at the LHC. For 5 fb^{-1} of accumulated integrated luminosity at the LHC, there could be ~ 500 doubly-charged \Sigma^{++} or \bar{\Sigma^{++}} fermions with mass M_\Sigma = 400 GeV, leading to interesting multi-lepton signatures. The neutral component of the fermion quintuplet, previously identified as minimal dark matter candidate, becomes unstable in the proposed seesaw setup. The stability can be restored by introducing a Z_2 symmetry, in which case neutrinos get mass only from radiative contributions.

The Dark Side of a Tera-Z Factory
Future Tera-Z runs at FCC-ee/CEPC could indirectly probe TeV-scale t-channel dark matter portals through one-loop and two-loop electroweak precision shifts, and in leptophilic models would be the only planned experime...

Thermal Leptogenesis in the BNT Model of Neutrino Mass
In the BNT neutrino-mass model, thermal leptogenesis can explain the observed baryon asymmetry with triplet masses above roughly 3.5e7 GeV in the hierarchical case and as low as 1.7 TeV with resonant enhancement.

Discovery prospects of a singly-charged scalar at $\mu$TRISTAN
A same-sign muon collider could discover the singly-charged scalar of Type-II seesaw through a lepton-flavor-violating process, and the final lepton flavor could distinguish normal from inverted neutrino mass ordering...
