By tracing the full $\\alpha_s$ and PDF dependences, including the parton-shower component, as well as the fixed-order scale uncertainties, we compute variational event weights on-the-fly, thereby greatly reducing the computational costs to obtain theoretical-uncertainty estimates.","authors_text":"Enrico Bothmann, Marek Sch\\\"onherr, Steffen Schumann","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2016-06-28T15:13:04Z","title":"Reweighting QCD matrix-element and parton-shower calculations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.08753","kind":"arxiv","version":3},"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:d584b1626766aa4e687951848ecaa02930c65208edf6767d7445243096f04c8c","target":"record","created_at":"2026-05-18T00:59:41Z","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":"9758551a0829103bc51e456c9a519cbcfac994870b96ce7bc18551c5687a836e","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2016-06-28T15:13:04Z","title_canon_sha256":"fc66be8a5b34b32cd9c0c1a7f67ae48103c4d80b738aac74c2499d8976053ac0"},"schema_version":"1.0","source":{"id":"1606.08753","kind":"arxiv","version":3}},"canonical_sha256":"f0ea05a88c50f642e6e86f9d09dd9c7874bcc72cb040891f15671ca551137889","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f0ea05a88c50f642e6e86f9d09dd9c7874bcc72cb040891f15671ca551137889","first_computed_at":"2026-05-18T00:59:41.851693Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:59:41.851693Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"atpOvfRaCKNfL+4TLkkDZtgkAA7AVPqm5tqXilhKKuW7OCQbHM1JPusVnNal7rVlGpDmcZ7vKxv2jV+8Yc2ZDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:59:41.852516Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.08753","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d584b1626766aa4e687951848ecaa02930c65208edf6767d7445243096f04c8c","sha256:f773718cc4bfc4218e5c8d18be3f1145c017cb11a7004742731fc6fa86ba7ad8"],"state_sha256":"28a4e7ea2652b230b015d6118ffbc2938aa15c2650ccd761185bb1ade875df6e"}
