Abstract
The hierarchy problem of the scalar sector of the standard model is reformulated, emphasizing the role of experimental facts that may suggest the existence of a new physics large mass scale, for instance indications of the instability of the matter, or indications in favor of massive neutrinos. In the see-saw model for the neutrino masses a hierarchy problem arises if the mass of the right-handed neutrinos is larger than approximatively $10^7$ GeV: this problem, and its possible solutions, are discussed.

The one-loop radiative correction to the upper bound on {ital m}{sub {ital h}}{sup 0} as a function of the free parameters of the MSSM is computed and it is found that the dominant correction is large and positive and grows like the top-quark mass.

It is found that the lepton-number-violating out-of-equilibrium decays of right-handed neutrinos combined with anomalous electroweak processes can generate the baryon number of the Universe, and that the scenario works for a wide range of parameters in the neutrino sector.
