We find that the SFP can give rise to a large effect to the asymmetry A_N owing to the large partonic hard cross sections with the large color factor, if the SFP function has a similar magnitude as the soft-gluo","authors_text":"Tetsuya Tomita, Yuji Koike","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2009-03-11T08:34:46Z","title":"Soft-fermion-pole contribution to single-spin asymmetry for pion production in pp collisions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0903.1923","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:e7113038b64f8c2aadc0eff5bd760b42cf808ff38cabf23cb2cd9cfd8bf6e069","target":"record","created_at":"2026-05-18T02:14:36Z","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":"04d07fc5517c25369f4659340a30964038992ae3ff8d87734f9126a570421cef","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2009-03-11T08:34:46Z","title_canon_sha256":"7ac2047ddc40e8e2993325f62bc52e85fcfcfd13d8a3b456e156c91568f33e49"},"schema_version":"1.0","source":{"id":"0903.1923","kind":"arxiv","version":2}},"canonical_sha256":"1c5ce984cc2793bbbd9fda0f8441fb62033763c3e8ed10e21a39b94958065627","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1c5ce984cc2793bbbd9fda0f8441fb62033763c3e8ed10e21a39b94958065627","first_computed_at":"2026-05-18T02:14:36.000324Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:14:36.000324Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ziykVQa8Nu25lp57ICMt/BsRTwE7K6alV79pZKGjFxsr4WfDbv8swu0Dr4ZBMtompnclmyRBFVLquhJsQ1bjAA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:14:36.000839Z","signed_message":"canonical_sha256_bytes"},"source_id":"0903.1923","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e7113038b64f8c2aadc0eff5bd760b42cf808ff38cabf23cb2cd9cfd8bf6e069","sha256:a4e7d18909fb17c6d7bb91a81bdc3a0ad53318a54c4b20cefa85df3b224cc923"],"state_sha256":"142ef00f8cc41afc98d2d620c4c321cd7983bddfa10b1ab3954226fe0bb9f0de"}
