The expressions are obtained by taking the field theory limits of (4,0) and (2,2) space-time supersymmetric string theory models. For each model we extract the contributions of the spin-1 and spin-2 N=4 supermultiplets running in the loop. We show that all of those constructions lead to the same four-dimensional result for the four-graviton amplitudes in pure supergravity even though they come from different string theory models.","authors_text":"Pierre Vanhove, Piotr Tourkine","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-08-06T19:46:26Z","title":"One-loop four-graviton amplitudes in N=4 supergravity models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1208.1255","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":"sha256:1ad47d25e248fb1e310a34180265a4a4d6e91537cd31d7181605cf41937c5abc","target":"record","created_at":"2026-05-18T03:22:27Z","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":"89cd89e5de23e3eb9fe440df22c4895f25aa8594e64878b60a7b127fcba1388e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-08-06T19:46:26Z","title_canon_sha256":"76ef83754438c3b0950e80d0a1b54b785b463bb651beed1f19bae0249b45c887"},"schema_version":"1.0","source":{"id":"1208.1255","kind":"arxiv","version":4}},"canonical_sha256":"0ccffe3675493720a110bbdf61f60b8a85ff751530f22d5aa3c4da63eb89371e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0ccffe3675493720a110bbdf61f60b8a85ff751530f22d5aa3c4da63eb89371e","first_computed_at":"2026-05-18T03:22:27.754238Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:22:27.754238Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AZb6inNp/GAwNaQF47I2kwpeWDOQpsfNMeFqkmwvewfHg71/rDnTKuYbBAVBW153fwDFKmV/H2EesG3EGSLTCg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:22:27.754675Z","signed_message":"canonical_sha256_bytes"},"source_id":"1208.1255","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1ad47d25e248fb1e310a34180265a4a4d6e91537cd31d7181605cf41937c5abc","sha256:3cea21794634adcdbf1feea9b75ec7a5e7f5c44b58ec8f15d13b774089527028"],"state_sha256":"eca42cbda86d8460166e255c061be35ae1f842200bd4ad786ba883a21058b073"}
