We explain the motivation for leptogenesis. We review the basic mechanism, and describe subclasses of models. We then focus on recent developments in the understanding of leptogenesis: finite temperature effects, spectator processes, and in particular the significance of flavor physics.","external_url":"https://arxiv.org/abs/0802.2962","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-04T17:09:58.350984+00:00","pith_arxiv_id":"0802.2962","created_at":"2026-05-10T23:00:49.991125+00:00","updated_at":"2026-07-04T17:09:58.350984+00:00","title_quality_ok":false,"display_title":"Leptogenesis","render_title":"Leptogenesis"},"hub":{"state":{"work_id":"7aa9783c-57f0-409f-96ac-75e49833a0f8","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":34,"external_cited_by_count":null,"distinct_field_count":3,"first_pith_cited_at":"2019-07-02T16:02:35+00:00","last_pith_cited_at":"2026-07-02T17:58:57+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-21T18:49:28.603675+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":13},{"context_role":"method","n":1}],"polarity_counts":[{"context_polarity":"background","n":13},{"context_polarity":"use_method","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
