Constraint on Seesaw Model Parameters with Electroweak Vacuum Stability

  • Published:
Russian Physics Journal Aims and scope

Within the standard model, the electroweak vacuum is metastable. We study how heavy right-handed neutrinos in seesaw model have impact on the stability through their loop effect for the Higgs potential. Requiring the lifetime of the electroweak vacuum is longer than the age of the Universe, the constraint on parameters such as their masses and the strength of the Yukawa couplings is obtained.
