This method allows us to calculate the fermionic part of the effective action (up to two-loop level) properly. The two-loop contribution to the effective potential for the Nambu-Jona-Lasinio model is calculated and is shown to vanish.","authors_text":"B.A.Faizullaev, M.M.Musakhanov","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"1994-12-07T12:39:28Z","title":"Two-Loop Effective Action for Theories with Fermions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9412066","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":"sha256:08e5013e63d3f6a01f0e18a232dbbd4b82e5fe0e85e8593abd759407fd45ce2b","target":"record","created_at":"2026-05-18T01:38:41Z","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":"69558e731bf4c2f1d4a9c5095034744ee5680c64223b9bc095e9164c9a1641ba","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"1994-12-07T12:39:28Z","title_canon_sha256":"868f44eb8622c54ea62032ff3c35d7e8ef3b2d8fa94ab900a1e719c8466c1080"},"schema_version":"1.0","source":{"id":"hep-th/9412066","kind":"arxiv","version":1}},"canonical_sha256":"af578aea86e9e550799fc562cef30f1f3d4580c9488670f2608745df4afe2a86","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"af578aea86e9e550799fc562cef30f1f3d4580c9488670f2608745df4afe2a86","first_computed_at":"2026-05-18T01:38:41.051889Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:38:41.051889Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ds61Ixa7/rUa8oluqsdYtOrfo/badQV/f/3tPaQm17b1TbHAxNxXPMGHL86ces/Opt6O/tq9zA7QAVawIZ4FCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:38:41.052393Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/9412066","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:08e5013e63d3f6a01f0e18a232dbbd4b82e5fe0e85e8593abd759407fd45ce2b","sha256:815ae72bc8f62af043bbd689533b1d676fbc0b775da1676b0cd56428ae67ddc8"],"state_sha256":"56d6e13efc15fdfc30c30b0b91aee71f30bb1c2dd85267e3528b20aec436291c"}
