Description
Can the lightest Higgs boson mass be affected by Heavy Majorana neutrinos
in an MSSM-seesaw scenario?
In order to answer this question I would like to explain the work done in
collaboration with S.Heinemeyer, M.J. Herrero and S.Penaranda where we
present a full diagrammatic computation of the one-loop corrections from the
neutrino/sneutrino sector to the renormalized neutral CP-even Higgs boson
self-energies.We explore the dependence on all the parameters involved, with
particular emphasis in the role played by the heavy
Majorana scale. For simplicity, we restrict ourselves to the one generation
case.We have used different renormalization schemes and compare the results.
In the mDRbar scheme, but not in the OS one, we find sizeable negative
corrections to $M_h$ in the region where the Majorana scale is large
($10^{13}-10^{15}$ GeV).
