摘要：

We study the connection between inflation and supersymmetry breaking in the context of an O'Raifeartaigh model which can account for both hybrid inflation and a true vacuum where supersymmetry is spontaneously broken. For a weakly coupled inflaton field, the dynamics during the inflationary phase can be determined by the supersymmetry breaking scale M-S similar to 10(10) GeV, even if H-1 much greater than m(3/2). The spectrum of density fluctuations is then almost scale invariant, with a spectral index n - 1 = O(M-G(2)/M-P(2)). The mass parameter Me of the O'Raifeartaigh model is determined by the COBE normalization for the cosmic microwave background to be the grand unification scale, M-G similar to 10(16) GeV.
