Mh in the MSSM-seesaw scenario with ILC precision    [PDF]

We review the computation of the one-loop radiative corrections from the
neutrino/ sneutrino sector to the lightest Higgs boson mass, Mh, within the
context of the so-called MSSM-seesaw scenario. This model introduces right
handed neutrinos and their supersymmetric partners, the sneutrinos, including
Majorana mass terms. We find negative and sizeable corrections to Mh, up to -5
GeV for a large Majorana scale, 10^{13}-10^{15} GeV, and for the lightest
neutrino mass in a range 0.1-1 eV. The corrections to Mh are substantially
larger than the anticipated ILC precision for large regions of the MSSM-seesaw
parameter space.
