Description
The destabilising effect of supergravity corrections on
traditional inflaton potentials is well known. Here I will offer a
possible solution based on the presense of an inflection point in the
flat direction potential for some Kahler interaction terms. We show that
for reasonable choices of the Kahler potential it is possible for a
vacuum energy density with no dynamics of its own, to induce an
extremely flat potential along the flat direction, and that this can be
suitable for producing the observed inflation with a total fine tuning
of no greater than one part in ten to the five.
