Using different nucleon distribution amplitudes, we find that the two-photon corrections to the $p\\bar{p} \\to e^+e^-$ cross sections in the momentum transfer range 5 - 30 GeV$^2$ is below the 1 % level.","authors_text":"Julia Guttmann, Marc Vanderhaeghen, Nikolai Kivel","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-01-31T13:54:41Z","title":"Study of Two-Photon Corrections in the $p\\bar{p} --> e+e-$ Process: Hard Rescattering Mechanism"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.5967","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":"sha256:35ca6ac5979bc31758775473a29aa2898850fb7d013723bbbf5838fda7c38c32","target":"record","created_at":"2026-05-18T02:22:41Z","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":"f9b99f4f77d8797ee018c3040f258c1cda3cf51e6ef9bf9e1d053987c4070993","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-01-31T13:54:41Z","title_canon_sha256":"a78eb85a5b58f89b29bd10605b2b46a52ca1c277a0eaae5a810986ef096308b2"},"schema_version":"1.0","source":{"id":"1101.5967","kind":"arxiv","version":1}},"canonical_sha256":"b89a5686a517d227428cb0eaa3dc3e594533d90ebdfcf55b9de1d2c6e3404a77","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b89a5686a517d227428cb0eaa3dc3e594533d90ebdfcf55b9de1d2c6e3404a77","first_computed_at":"2026-05-18T02:22:41.772658Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:22:41.772658Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"o176UGM5F6xjIbGnNdpRntOy7nc7bVBOKfH9Y3hw1eOP6P21pBTMCKkcRC1RrJ6vk8mJJhOcdXaZTlghY0ypAw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:22:41.773257Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.5967","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:35ca6ac5979bc31758775473a29aa2898850fb7d013723bbbf5838fda7c38c32","sha256:19bb21aafb08e29b424fb199659af55063f9e9d61825655e75a5c1893caea7f4"],"state_sha256":"6ba5f845ac1129222b289e0a536f140dffe9aa198d91282fe7c0ef06509ad10d"}
