Initial conditions for supersymmetric inflation

We perform a numerical investigation of the field evolution in the supersymmetric inflationary model based on radiative corrections. Supergravity corrections are also included. We find that, out of all the examined initial data, only about 10{percent} give an adequate amount of inflation and can be considered as {open_quotes}natural.{close_quotes} Moreover, these successful initial conditions appear scattered and more or less isolated. {copyright} {ital 1997} {ital The American Physical Society}
