Without the deformations, this model exhibits chiral symmetry breaking without confinement. It is usually asserted that the massless Schwinger model is always deconfined and a string tension emerges only when a mass for the fermion field is turned on. We show that in the presence of these four-fermion operators, the massless theory can in fact confine. One of the four-fermion deformations is chirally neutral, and is a marginal deformation. The other operator can be relevant or irrelevant, a","authors_text":"Aleksey Cherman, Arkady Vainshtein, Mikhail Shifman, Mithat Unsal, Theodore Jacobson","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2022-03-24T16:24:54Z","title":"Four-fermion deformations of the massless Schwinger model and confinement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2203.13156","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":"sha256:1e91ef9b010bc127386eea8f467caba9e3d7f19efd6ba3ebbe446424aa9f36c4","target":"record","created_at":"2026-07-05T05:37:36Z","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":"749ef134bc6bc0896db165fd62daf8f3e3adfbcc20212a8dba66d3f511df07db","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2022-03-24T16:24:54Z","title_canon_sha256":"9088417642fc2ead66369ea16f167ac46742c470c2a827d0099a43b1a1fdd082"},"schema_version":"1.0","source":{"id":"2203.13156","kind":"arxiv","version":2}},"canonical_sha256":"5cf139200bb49fbaadd47331043c80a10bd1e881d1edd1a6b532b7322ae88455","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5cf139200bb49fbaadd47331043c80a10bd1e881d1edd1a6b532b7322ae88455","first_computed_at":"2026-07-05T05:37:36.476228Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:37:36.476228Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PCY2BKAal/pZ0Uz9yK+xgbUjAjw5G9PObYpTdXUeVvMYcjCcoCy5UVR5RdbUJoDoha+2fcfLCKyAMg9nV5hrCw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:37:36.476729Z","signed_message":"canonical_sha256_bytes"},"source_id":"2203.13156","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1e91ef9b010bc127386eea8f467caba9e3d7f19efd6ba3ebbe446424aa9f36c4","sha256:ee7c761b0722a66a6f9310e3eb30715d7ce5c10b76f00af44ae4ed0a05c0cd61"],"state_sha256":"6202839794adfa134ec0658484a4a55087a803dda8b1eae4b979deba3704ebd3"}
