Query: Electroweak Absolute, Meta-, and Thermal Stability in Neutrino Mass
  Models   We analyze the stability of the electroweak vacuum in neutrino mass models
containing right handed neutrinos or fermionic isotriplets. In addition to
considering absolute stability, we place limits on the Yukawa couplings of new
fermions based on metastability and thermal stability in the early Universe.
Our results reveal that the upper limits on the neutrino Yukawa couplings can
change significantly when the top quark mass is allowed to vary within the
experimental range of uncertainty in its determination.
