For an exploratory study of this method, we evaluate a scattering length of $I=2$ S-wave two pions by the use of the on-shell scattering amplitude. Our result is confirmed to be consistent with the value obtained from the conventional finite volume method. The half-off-shell scattering amplitude is also evaluated.","authors_text":"Takeshi Yamazaki, Yusuke Namekawa","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2017-12-29T08:08:09Z","title":"Scattering amplitude from Bethe-Salpeter wave function inside the interaction range"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.10141","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":"sha256:90424a43a06e25d07f64c59a7eaff2fe819c5807a056883aa5375a4f0d5a6bd4","target":"record","created_at":"2026-05-18T00:08:36Z","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":"735b79d1eb315d042f75593bba99b14fb255a751608f71c6a457f12c54174fdd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2017-12-29T08:08:09Z","title_canon_sha256":"2de2c0964314c77d26b6a1a16783d7a07e809206e3367c091ac5013ec55bb26f"},"schema_version":"1.0","source":{"id":"1712.10141","kind":"arxiv","version":2}},"canonical_sha256":"9b9be2f1ef0e0e8f830e15cca2a0951dbd1fd47a1646e16ed4cece83c56c494c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9b9be2f1ef0e0e8f830e15cca2a0951dbd1fd47a1646e16ed4cece83c56c494c","first_computed_at":"2026-05-18T00:08:36.161704Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:08:36.161704Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BkwgKJFicaH43lkRWUer+q64IxWclUqZBohU58skUt1HhwLZ7uLzVXuGnNoVI8zer9gxQTetxJDdN+oePXEJAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:08:36.162309Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.10141","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:90424a43a06e25d07f64c59a7eaff2fe819c5807a056883aa5375a4f0d5a6bd4","sha256:0dca1562649a58eabde12a9de244de0e143ab3be1249035535b61e892925eff4"],"state_sha256":"8a72698b79d21e018c88371706dff38f69b82925c39e75229100ad132f6899ec"}
