A dynamical mass is predicted for the gluon and the lattice data are reproduced fairly well by a second-order expansion, without any free parameter. The effective running coupling is small in the IR and the approximation can be improved by inclusion of higher order terms.","authors_text":"Fabio Siringo","cross_cats":["hep-lat","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2015-07-20T15:52:54Z","title":"Perturbation theory of non-perturbative QCD"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1507.05543","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:f859de992170b1237190c3d0298f70f09e3aef220dfa45fc8d5a04daf6415702","target":"record","created_at":"2026-05-18T01:36:36Z","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":"8f1a91db2eb775b305758c4cb5bba1c68c575ae9d46903a1d078f57f33e20116","cross_cats_sorted":["hep-lat","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2015-07-20T15:52:54Z","title_canon_sha256":"795cf5dfedf2707349159a9031a2388e296fe8e114b7598ad19761f410dd0fdd"},"schema_version":"1.0","source":{"id":"1507.05543","kind":"arxiv","version":1}},"canonical_sha256":"4100e93c70127db3c9f68c714715c6cdb793c2b65f5c0b42899daa78accebbd1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4100e93c70127db3c9f68c714715c6cdb793c2b65f5c0b42899daa78accebbd1","first_computed_at":"2026-05-18T01:36:36.543104Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:36:36.543104Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BddQE7XdYHMJJuLB77hxxRHOZqIyDKZcy+KEs4tDAkwfgBHZCWd7E8RLLoZtGhVpp6aDtNL39XYP4O3czuQICQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:36:36.543550Z","signed_message":"canonical_sha256_bytes"},"source_id":"1507.05543","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f859de992170b1237190c3d0298f70f09e3aef220dfa45fc8d5a04daf6415702","sha256:c3083298878724185d689082b9c6f3e49d734d78c9dca1d99ba3860f6807b290"],"state_sha256":"1ee49e3d73f9cbbeec2c1351bdad3d380d05ab0a2785c6f85d3cf04c6b082747"}
