In particular we discuss how the parton showers and multiparton interactions are generated with a resolved photon beam and what is the relative contribution from direct processes in different kinematical regions. As an application we show comparisons to data for charged-particle production in e+e- and ep collisions at LEP and HERA. We consider also photoproduction of dijets comparing to data for ep collisions at HERA and discuss about possibility to further constrai","authors_text":"Ilkka Helenius","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-08-31T14:53:34Z","title":"Photon-photon and photon-hadron processes in Pythia 8"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1708.09759","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:8ae5fb8507dfb7d44a7b0474b884c80cb8f17e90f9d4362e81de1221ec031489","target":"record","created_at":"2026-05-18T00:36:15Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"551a93780fbccb3bca6c4eed85be600d8d4e246baa85f4c6a3c85f6774a552b6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-08-31T14:53:34Z","title_canon_sha256":"026cbbe5fa2cba7d9ea121ebd752b7b5148d5e5090270b3e4769b70581df48ad"},"schema_version":"1.0","source":{"id":"1708.09759","kind":"arxiv","version":1}},"canonical_sha256":"b4add1721d1198713aef70af3c782a155e728f962615430480593eeef8ea9f0d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b4add1721d1198713aef70af3c782a155e728f962615430480593eeef8ea9f0d","first_computed_at":"2026-05-18T00:36:15.193708Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:36:15.193708Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qBHTfojAptSbMBg0dJGk4MypQK+HHRIW7Dw4QLL0rYBeGGP+OiSBPk1OFk+ZZxXDhfyji6i0gQjp11CSWR72Cw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:36:15.194218Z","signed_message":"canonical_sha256_bytes"},"source_id":"1708.09759","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8ae5fb8507dfb7d44a7b0474b884c80cb8f17e90f9d4362e81de1221ec031489","sha256:c33ad16b43e5768096ee0babf31e4a0d9a66bb0001ca1de6e8b7ebbfe8ff0a41"],"state_sha256":"713ab06e1a188d9e574eefc79e35f45324d117a6312273fe2361e84aa80b4256"}
