Gravity-improved metastability bounds for the Type-I seesaw mechanism
Abstract Right-handed neutrinos (RHN) destabilize the electroweak vacuum by increasing its decay rate. In the SM, the latter is dominated by physics at the RG scale at which λ reaches its minimum, μ ∗ SM $$ {\mu}_{\ast}^{\textrm{SM}} $$ ∼ 1017 GeV. For large neutrino Yukawa coupling Y ν , RHNs can p...
