Sažetak (engleski)
We propose a new seesaw model based on a fermionic hypercharge-zero weak quintuplet in conjunction with an additional scalar quadruplet which attains an induced vacuum expectation value. The model provides both tree-level seesaw ~v6/M5 and loop-suppressed radiative ~(1/16π2) · v2/M contributions to active neutrino masses. The empirical masses m 101 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 Σ++ or Σ++overbar fermions with mass MΣ = 400 GeV, leading to interesting multilepton signatures. The neutral component of the fermion quintuplet, previously identified as a minimal dark matter candidate, becomes unstable in the proposed seesaw setup. The stability can be restored by introducing a Z2 symmetry, in which case neutrinos get mass only from radiative contributions.
