We present state-of-the-art calculations of viscous photon emission from nuclear collisions at RHIC and LHC. Thermal photons anisotropic flow coefficients v_n are computed, both with and without accounting for viscous corrections to the standard thermal emission rates. These corrections are found to have a larger effect on the v_n coefficients than the viscous suppression of hydrodynamic flow anisotropies. For thermal photons, the ratio v_2{SP}/v_3{SP} shows stronger sensitivity to the quark-gluon plas","authors_text":"Charles Gale, Chun Shen, Jean-Francois Paquet, Ulrich Heinz","cross_cats":["hep-ph","nucl-ex"],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"nucl-th","submitted_at":"2014-03-28T22:22:13Z","title":"Thermal photon anisotropic flow serves as a quark-gluon plasma viscometer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.7558","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":"sha256:5516d7e3a0706049a115d2853000d7d64e50b6c518f14c2b8ce86228419289e5","target":"record","created_at":"2026-05-18T01:29:11Z","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":"f21f7b2a2b541dcb4f3806cce1e2b6b6e0ab6ff5ac591f16a1ee79d7d1b7f316","cross_cats_sorted":["hep-ph","nucl-ex"],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"nucl-th","submitted_at":"2014-03-28T22:22:13Z","title_canon_sha256":"28bdff5ecbc3313938ee36fe54cfee33016266d00c704ec7d3d400560a62edf8"},"schema_version":"1.0","source":{"id":"1403.7558","kind":"arxiv","version":1}},"canonical_sha256":"9bfa8ebf956b56b77418588146525bd1a38c3560edd47e26b031b16e43fbcf50","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9bfa8ebf956b56b77418588146525bd1a38c3560edd47e26b031b16e43fbcf50","first_computed_at":"2026-05-18T01:29:11.472371Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:29:11.472371Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Wa+Mvwb1WWZgivo3EdzZcqThwPU6G+Z2WbdeV1ud9knvGclEQLfaulJ019FNuZJSM5t9rW66IzDYp1dTDjypDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:29:11.473021Z","signed_message":"canonical_sha256_bytes"},"source_id":"1403.7558","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5516d7e3a0706049a115d2853000d7d64e50b6c518f14c2b8ce86228419289e5","sha256:6e8ee8d3babc6bbf914e9998235808ed1e937e2d889da8e081c797cca3bff535"],"state_sha256":"c4eb4799c78f1a2ccc7741ac77eb6099928bc5773e71288dacfa27bcd13b597b"}
