Our results show that future CMB polarization experiments, such as PLANCK and CMBpol will make a possible test on this class of model for leptogenesis.","primary_cat":"hep-ph","cross_cats":["astro-ph"],"submitted_at":"2004-06-24T09:08:45+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"A derivative coupling of ln R to the electromagnetic Chern-Simons term produces cosmological birefringence that rotates CMB polarization, and a Fisher forecast shows CMBpol could detect the coupling at the level implied by gravitational leptogenesis.","novelty_score":5.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":29,"_links":{"html":"https://pith.science/paper/hep-ph/0406269","verdict":"/api/v1/verdicts/hep-ph/0406269"}}
