We allow for finite pulse duration, while still treating the laser fields nonperturbatively in strong-field QED. Our approach reveals explicitly the individual contributions of the one-step and two-step processes. We also expose the role gauge invariance plays in the amplitudes and discuss the relation between our results and the optical theorem.","authors_text":"Anton Ilderton","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2010-11-17T21:02:01Z","title":"Trident pair production in strong laser pulses"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1011.4072","kind":"arxiv","version":2},"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":"sha256:3c4aa1a379d42ccb001f9eda616c4ce56384b8a00bc30d31a8edff211f28b36e","target":"record","created_at":"2026-05-18T04:30:13Z","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":"6ccc48a193a467333fe3f1c5d42d645950dcbefbb30debc487ed5aa3df371d4c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2010-11-17T21:02:01Z","title_canon_sha256":"ac3f66d2ed73275ec6d8cb95c6224bb934dfb72f9edaf48d4fc40b5d83b4b8b7"},"schema_version":"1.0","source":{"id":"1011.4072","kind":"arxiv","version":2}},"canonical_sha256":"4e63ba6afad8d8fa44568fe9570df05f13ab70e599000c0ebb7d3fca504fc260","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4e63ba6afad8d8fa44568fe9570df05f13ab70e599000c0ebb7d3fca504fc260","first_computed_at":"2026-05-18T04:30:13.641876Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:30:13.641876Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jzhly/XmcE0+l3t6N2MPLb3rLn9fbT9FroF08E7EftFU7l3cvIuOfwpXptj6TFNsvgxDDY+0SRd4cVLPdgyWDA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:30:13.642682Z","signed_message":"canonical_sha256_bytes"},"source_id":"1011.4072","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3c4aa1a379d42ccb001f9eda616c4ce56384b8a00bc30d31a8edff211f28b36e","sha256:fb0b8ee0cda77685c2a3771877c8da38c76c05b489b892e84c57397d9517be1c"],"state_sha256":"37a0746bf72f9ee7aa9aa9ea9a08008629f4280f73e66cc4e783d628e8b79aa2"}
