{"arxiv_id":"hep-ph/0307081","title":"Leptogenesis from Supersymmetry Breaking","abstract":"We show that soft supersymmetry breaking terms involving the heavy sneutrinos can lead to sneutrino-antisneutrino mixing and to new sources of CP violation, which are present even if a single generation is considered. These terms are naturally present in supersymmetric versions of leptogenesis scenarios, and they induce indirect CP violation in the decays of the heavy sneutrinos, eventually generating a baryon asymmetry. This new contribution can be comparable to or even dominate over the asymmetry produced in traditional leptogenesis scenarios.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2003-07-07T06:46:22+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":null,"confidence":null,"one_line_summary":null,"novelty_score":null,"correctness_risk":null,"formal_verification":null,"upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":7,"_links":{"html":"https://pith.science/paper/hep-ph/0307081","verdict":"/api/v1/verdicts/hep-ph/0307081"}}
