The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCD-based models. This physics input is summarized here, for areas such as hard subprocesses, initial- and final-state parton showers, underlying events and beam remnants, fragmentation and decays, and much more. Furthermore, extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest.","external_url":"https://arxiv.org/abs/hep-ph/0603175","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-06-26T12:09:28.171025+00:00","pith_arxiv_id":"hep-ph/0603175","created_at":"2026-05-10T09:13:29.665959+00:00","updated_at":"2026-06-26T12:09:28.171025+00:00","title_quality_ok":false,"display_title":"PYTHIA 6.4 Physics and Manual","render_title":"PYTHIA 6.4 Physics and Manual"},"hub":{"state":{"work_id":"08538d78-d555-4175-a212-24ade7380c74","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":43,"external_cited_by_count":null,"distinct_field_count":6,"first_pith_cited_at":"2007-09-13T17:49:16+00:00","last_pith_cited_at":"2026-06-20T12:14:52+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":"2026-06-27T11:26:00.572542+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"method","n":11},{"context_role":"background","n":9}],"polarity_counts":[{"context_polarity":"use_method","n":11},{"context_polarity":"background","n":9}],"runs":{},"summary":{},"graph":{},"authors":[]}}
