Scientific paper

The authors show that a single uncharged chiral superfield, canonically coupled to N = 1 supergravity with vanishing superpotential, naturally drives inflation in the early universe for a class of simple Kähler potentials. Inflation occurs due to the one-loop generation of a Kähler anomaly proportional to R2. The coefficient of this R2 term is of the correct magnitude to describe all aspects of an inflationary cosmology, including sufficient amplitude perturbations and reheating. Higher order terms proportional to Rn for n ≥ 3 are naturally suppressed relative to the R2 term and, hence, do not destabilize the theory.
