摘要: Abstract We consider the effect of primordially produced gravitons on anisotropy cosmological microwave background radiation. For a universe that includes phase exponential expansion, we derive an upper limit upon associated vacuum energy density. This coincides with one found by Rubakov et al., but our calculations differ from theirs in several important respects. Recent supersymmetric inflationary model universes are compatible this limit, models which expansion is caused trace-anomaly effects appear to be ruled out. finally provide detailed analysis harmonic content and show relevance harmonics relatively large l.
