Field theories with space-time noncommutativity do not have a unitary S-matrix. Field theories with only space noncommutativity are perturbatively unitary. This can be understood from string theory, since space noncommutative field theories describe a low energy limit of string theory in a background magnetic field. On the other hand, there is no regime in which space-time noncommutative field theory is an appropriate description of string theory. Whenever space-time noncommutative field theory becomes relevant massiv","authors_text":"Jaume Gomis, Thomas Mehen (Caltech)","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2000-05-14T23:40:00Z","title":"Space-Time Noncommutative Field Theories And Unitarity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0005129","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":"sha256:23070cc60eb2cb01eeb5918cbe31d82978cbecd851cd60ee0681b056b9a25b4b","target":"record","created_at":"2026-07-04T16:20:46Z","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":"e857af2ba0f0fcf2c341e3aa7f81ea36729066e14c54919ecad2d307f7c3ac28","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"2000-05-14T23:40:00Z","title_canon_sha256":"69979937177946a5fa8da037973e56ec85698bf716e0a53e74155112be635f98"},"schema_version":"1.0","source":{"id":"hep-th/0005129","kind":"arxiv","version":2}},"canonical_sha256":"cf685e3091286708f2971983e5af152cb0e6861d71ae2dccb60db549f7acabec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cf685e3091286708f2971983e5af152cb0e6861d71ae2dccb60db549f7acabec","first_computed_at":"2026-07-04T16:20:46.440028Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:20:46.440028Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IuNRDKBj2uLaWYoAwsO9GIW1CD/xO5pd6edLRYn/x5CnLtHAU3TwLsBuh2lc8vzHN93Uq/gHW9YUA0/wsxgpBw==","signature_status":"signed_v1","signed_at":"2026-07-04T16:20:46.440438Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0005129","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:23070cc60eb2cb01eeb5918cbe31d82978cbecd851cd60ee0681b056b9a25b4b","sha256:07de2ed19f4683b590bfc05da4794152e53eceed87b23ae0febfb0f31347ff55"],"state_sha256":"05036b61cabf22e944b408ac38ea022621f65e903bbcb3d634f4f9a362f9b595"}
