It calculates the underlying Feynman rules and outputs them to a form appropriate for various programs such as CalcHEP, FeynArts, MadGraph, Sherpa and Whizard. Since the original version, many new features have been added: support for two-component fermions, spin-3/2 and spin-2 fields, superspace notation and calculations, automatic mass diagonalization, completely general FeynArts output, a new universal FeynRules output interface, a new Whizard interface, automatic 1 to 2 decay width calculation, improved speed and efficiency, new guidelines for validation and a new web-based validation package. With this feature set, FeynRules enables models to go from theory to simulation and comparison with experiment quickly, efficiently and accurately.","external_url":"https://arxiv.org/abs/1310.1921","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-04T17:29:59.707700+00:00","pith_arxiv_id":"1310.1921","created_at":"2026-05-09T06:35:40.208104+00:00","updated_at":"2026-07-04T17:29:59.707700+00:00","title_quality_ok":true,"display_title":"FeynRules 2.0 - A complete toolbox for tree-level phenomenology","render_title":"FeynRules 2.0 - A complete toolbox for tree-level phenomenology"},"hub":{"state":{"work_id":"4b2e5214-c9b2-40a9-a026-61d4397bd05f","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":73,"external_cited_by_count":null,"distinct_field_count":3,"first_pith_cited_at":"2014-05-01T20:24:46+00:00","last_pith_cited_at":"2026-06-27T03:49:26+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":"2026-08-21T17:59:26.364616+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":13},{"context_role":"method","n":10}],"polarity_counts":[{"context_polarity":"background","n":13},{"context_polarity":"use_method","n":10}],"runs":{},"summary":{},"graph":{},"authors":[]}}
