A brief introduction to the concept of spin is provided along with a historical review of some of the most important problems and accomplishments in higher spin theory, followed by a review of familiar lower spin theories. Using a particularly elegant formalism, we examine the free higher spin theory and the theory coupled to a generic external current. For both of these theories, we review their constrained and the unconstrained formulation, focusing o","authors_text":"Ivan Vukovi\\'c","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-09-05T01:18:31Z","title":"Higher spin theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.02179","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:fc6b7cffc8642f87a05296e75f2152bf8eb120c2c1f017cf4e3f6b45cb05c13e","target":"record","created_at":"2026-05-18T00:06:17Z","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":"23614d82dba2cdeaf7d6e4371ca25224bc38398880588f0f79d168cc77f07411","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-09-05T01:18:31Z","title_canon_sha256":"c8eae994d0edd0ebcc34de11f685ea040fe7dc0afea2efe30ecb1e80ac03ba34"},"schema_version":"1.0","source":{"id":"1809.02179","kind":"arxiv","version":1}},"canonical_sha256":"e5c5d9afed967445609d704f02eed32b1b8433c5c206a9bab194174ac12e082c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e5c5d9afed967445609d704f02eed32b1b8433c5c206a9bab194174ac12e082c","first_computed_at":"2026-05-18T00:06:17.734228Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:17.734228Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gB2cqApTFpPPdezrm6e2K588ouqBxKqN4nuRU/RQi0iOrXIlrnfRDOujKcw4PFWxPqHyGszH6d332LgDxFHEDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:17.734908Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.02179","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fc6b7cffc8642f87a05296e75f2152bf8eb120c2c1f017cf4e3f6b45cb05c13e","sha256:a3850d23de3019427297e835db971ca61a54171e1f70fbcce300c6a221bc5fed"],"state_sha256":"dff778ab8198ef6eff957252ab704bc60401299bcd28468ebc022147e471998a"}
