  We investigate cosmological consequences of an inflationary model which
incorporates a generic seesaw extension (types I and II) of the Standard Model
of Particle Physics. A non-minimal coupling between the inflaton field and the
Ricci scalar is considered as well as radiative corrections at one loop order.
This connection between the inflationary dynamics with neutrino physics results
in a predictive model whose observational viability is investigated in light of
the current cosmic microwave background data, baryon acoustic oscillation
observations and type Ia supernovae measurements. Our results show that the
non-minimal coupled seesaw potential provides a good description of the
observational data when radiative corrections are positive. Such result favours
the type II seesaw mechanism over type I and may be an indication for physics
beyond the Standard Model.
