We provide a gauge-independent criterion for baryon number preservation in place of the conventional (gauge-dependent) criterion needed for successful electroweak baryogenesis. We also review the arguments leading to the preservation criterion and analyze several sources of theoretical uncertainties in obtaining a numerical bound. In various beyond the standard model scenarios, a realistic perturbative treatment will likely require knowledge of the complete two-loop finite temperature effective potential and the one-loop sphaleron rate.","external_url":"https://arxiv.org/abs/1101.4665","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-09T08:05:16.230513+00:00","pith_arxiv_id":"1101.4665","created_at":"2026-05-15T09:19:53.811227+00:00","updated_at":"2026-07-11T11:50:26.030339+00:00","title_quality_ok":true,"display_title":"Baryon Washout, Electroweak Phase Transition, and Perturbation Theory","render_title":"Baryon Washout, Electroweak Phase Transition, and Perturbation Theory"},"hub":{"state":{"tier_text":"hub","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":10,"external_cited_by_count":null},"tier":"hub","role_counts":[{"context_role":"background","n":1}],"polarity_counts":[{"context_polarity":"background","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
