{"arxiv_id":"hep-ph/0501007","title":"Relaxing Constraints on Inflation Models with Curvaton","abstract":"We consider the effects of the curvaton, late-decaying scalar condensation, to observational constraints on inflation models. From current observations of cosmic density fluctuations, severe constraints on some class of inflation models are obtained, in particular, on the chaotic inflation with higher-power monomials, the natural inflation, and the new inflation. We study how the curvaton scenario changes (and relaxes) the constraints on these models.","primary_cat":"hep-ph","cross_cats":["astro-ph"],"submitted_at":"2005-01-03T08:22:12+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"HIGH","one_line_summary":"Adding a curvaton reopens parameter space for quartic and sextic chaotic inflation and for natural inflation, which CMB data had excluded, but not for higher-power chaotic models or for supersymmetric new inflation.","novelty_score":4.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":14,"_links":{"html":"https://pith.science/paper/hep-ph/0501007","verdict":"/api/v1/verdicts/hep-ph/0501007"}}
