Lightest Higgs boson mass in split supersymmetry with the seesaw mechanism
Lightest Higgs boson mass in split supersymmetry with the seesaw mechanism
In the minimal supersymmetric standard model extended by including right-handed neutrinos with seesaw mechanism, the neutrino Yukaka couplings can be as large as the top-quark Yukawa couplings and thus the neutrino/sneutrino may cause sizable effects in Higgs boson self-energy loops. Our explicit one-loop calculations show that the neutrino/sneutrino effects may …
