Scientific paper

A new type of inflation is presented in the heterotic E8 x E8 superstring model. The inflation is identified with the 'Polonyi' field tau, which is related to the radius of the internal space. Radiative corrections to the gluino condensation potential are supposed to give rise to a suitable potential which is adjusted to vanish at the minimum by addition of a constant Delta V, whose magnitude is fixed by the requirement that density perturbations are of the right order. Reheating is due to the decay of the 'Polynyi' field tau and/or to the production of light particles through its oscillations.
