We show that in these models the two-loop amplitude has a prefactor of d^2R^4. This implies a non-renormalisation theorem for the R^4 term, which forbids the appearance of a three-loop ultraviolet divergence in four dimensions in the four-graviton amplitude. We connect the special nature of the R^4 term to the U(1) anomaly of pure N=4 supergravity.","authors_text":"Pierre Vanhove, Piotr Tourkine","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-02-16T20:52:34Z","title":"An R^4 non-renormalisation theorem in N=4 supergravity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1202.3692","kind":"arxiv","version":4},"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":"sha256:6ef710023eb2124a1310e4243cfca6ef3ea217ab841e269218f23002a7cf9336","target":"record","created_at":"2026-05-18T01:58:24Z","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":"53dbddf45d4d1b02f1e43502f3e87ec608cc8a34557335b3053f8b82b9821886","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-02-16T20:52:34Z","title_canon_sha256":"a897864cc6503deff8a4e69be89e7de571487a90d5e9f098ab1e30beddbf6e2d"},"schema_version":"1.0","source":{"id":"1202.3692","kind":"arxiv","version":4}},"canonical_sha256":"9df32dfa07a7f44bf4bce74a856414850a4c6d41ffbd6d5b4aaaf59b14eeb3fd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9df32dfa07a7f44bf4bce74a856414850a4c6d41ffbd6d5b4aaaf59b14eeb3fd","first_computed_at":"2026-05-18T01:58:24.320840Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:58:24.320840Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pnS8aVIyBGfim2jC2pmcmahHGTFWG0ytDT+HtVkHgtdqzem2rrFG/zoYPGn5ZbJ5So3Zuh6SgjsPNoRYb4lZAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:58:24.321327Z","signed_message":"canonical_sha256_bytes"},"source_id":"1202.3692","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6ef710023eb2124a1310e4243cfca6ef3ea217ab841e269218f23002a7cf9336","sha256:dfb57a80bebd069bf650b69aa8b9823cc0afc8509c555aedd7cde8352611626f"],"state_sha256":"542b38e116b67a91f5a92df977f6bca5e5fea7117eaf0c9117d97d1277868b77"}
