We start by providing a pedagogical review of the $\\theta$-angle physics for Quantum Chromodynamics (QCD) including also the axion properties. We then move to analyse composite extensions of the standard model elucidating the interplay between the new $\\theta$-angle with the QCD one. We consider first QCD-like dynamics and then generalise it to consider several kinds of new strongly coupled gauge theories with fermions transforming according to d","authors_text":"DIAS), Francesco Sannino (CP3-Origins, Paolo Di Vecchia (NBI & NORDITA)","cross_cats":["hep-lat","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2013-10-03T12:20:56Z","title":"The Physics of the $\\theta$-angle for Composite Extensions of the Standard Model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1310.0954","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:c80e20ee9841a8930aeb8c8a2369f7da02794377428023373000f3f4b845f44f","target":"record","created_at":"2026-05-18T03:09:47Z","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":"816a741a7d70fc2cb841570be1f3369f8f9a0ae164efffdd9c130b6c680db303","cross_cats_sorted":["hep-lat","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2013-10-03T12:20:56Z","title_canon_sha256":"eb07579aa667df954cabe01b04c08d43a9173affd3a953df2261d83e1ecb9a3b"},"schema_version":"1.0","source":{"id":"1310.0954","kind":"arxiv","version":2}},"canonical_sha256":"e34e698d1068b7069da44c94d41dee4861a9aac062c5eadb0afd96c8fb407e73","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e34e698d1068b7069da44c94d41dee4861a9aac062c5eadb0afd96c8fb407e73","first_computed_at":"2026-05-18T03:09:47.530793Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:09:47.530793Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Pux2ZCKM2pcKsZRtzt+/545nkqcgOt+/f7/z66k5B/qjehKelD1GEcFY+RfKKLhHF4NEJ1mGgOkxSKIuob8XDw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:09:47.531665Z","signed_message":"canonical_sha256_bytes"},"source_id":"1310.0954","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c80e20ee9841a8930aeb8c8a2369f7da02794377428023373000f3f4b845f44f","sha256:007afe6c8999a3d6f67639aed62096e1336461cb934c20f4967048345a6e9f8c"],"state_sha256":"a40e4ae281d471d0bc28077c880be042e7dc20d378f0fe59062cc62fafcb1089"}
