Once the harmonic gauge condition is implemented, as customary, according to the Faddeev-Popov procedure, the gauge fixed action still depends on one gauge parameter. Consequently, the harmonic gauge appears to be a class of conditions, rather than a particular one. This allows to give a physical motivation for the covariant harmonic gauge(s), which emerges when the gravitational perturbation is given a mass term. In fact, for a particular choice of harmonic gauge, we find a the","authors_text":"Giulio Gambuti, Nicola Maggiore","cross_cats":["hep-th"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2020-06-08T05:22:26Z","title":"A note on Harmonic Gauge(s) in Massive Gravity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2006.04360","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:ee7b7cb964989ca330ef963320ca0171db53720bf520c645ea95c48a04fd59e9","target":"record","created_at":"2026-07-05T01:11:47Z","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":"a570f47f2ee0b7fa496662dbc747bf1096e9c7bc9291a0f771a336d6d9bfea5b","cross_cats_sorted":["hep-th"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2020-06-08T05:22:26Z","title_canon_sha256":"07f207dc274e5b2615d782e999e9eebeb396878cb19bb49e063f5a09cc13c399"},"schema_version":"1.0","source":{"id":"2006.04360","kind":"arxiv","version":2}},"canonical_sha256":"f5baf6fdcf39facd04162517cfb7a3c3875e5a49bef26a3878985221af8043e3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f5baf6fdcf39facd04162517cfb7a3c3875e5a49bef26a3878985221af8043e3","first_computed_at":"2026-07-05T01:11:47.807713Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:11:47.807713Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GFtWHhbxs6r/qtFOm9JZr1WoUEmosMmEntyzc5LowEXUq4wKHRVuJNdk7xPGyhyBwgAXOkp10uPB6XR8qeQuCg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:11:47.808140Z","signed_message":"canonical_sha256_bytes"},"source_id":"2006.04360","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ee7b7cb964989ca330ef963320ca0171db53720bf520c645ea95c48a04fd59e9","sha256:987b351d0886b350a0af1196e354053482959e5095f95936c556b9fdfe033447"],"state_sha256":"0ed98605916094b8f403391e3c6e207663932f3982da1fe4d66bfc91994f378d"}
