We consider infinitesimal K\\\"{a}hler deformations of the Calabi-Yau background and derive the complete set of four-derivative couplings quadratic in these fluctuations coupled to gravity. In particular, we find four-derivative couplings of the K\\\"{a}hler moduli fields in the four-dimensional effective supergravity theory, which are referred to as friction couplings in the ","authors_text":"Matthias Weissenbacher","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2016-07-13T20:13:30Z","title":"On four-derivative terms in IIB Calabi-Yau orientifold reductions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.03913","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:ec279ef9a070b42a66c3807483c8c260f49bdc36aedf19069d0dc430a65c4af1","target":"record","created_at":"2026-05-18T00:44:00Z","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":"470106ecbefdcf0b51a0dc17a50373e3459f2bd409c759f8d15e9e98e31dfc35","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2016-07-13T20:13:30Z","title_canon_sha256":"82021ac1b0a689098a52dff3a36d8a6648e3d4e3778eaf87171008ae8d00cf1b"},"schema_version":"1.0","source":{"id":"1607.03913","kind":"arxiv","version":2}},"canonical_sha256":"9782bf88aca2c5afa5fd50f549f117f64d71d87007ae98da88db79a71350a7cb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9782bf88aca2c5afa5fd50f549f117f64d71d87007ae98da88db79a71350a7cb","first_computed_at":"2026-05-18T00:44:00.682019Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:44:00.682019Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gDqppgCrUH9A7liqK4oGp1Yc6hMCP/P//BSiuQ8twv5EgpN+Y1xjhLdbVjnewOFj8VEA67uiKrqPyEDHJvI3Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:44:00.682733Z","signed_message":"canonical_sha256_bytes"},"source_id":"1607.03913","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ec279ef9a070b42a66c3807483c8c260f49bdc36aedf19069d0dc430a65c4af1","sha256:c7be5b93dad73e67a1de5ffc70df9fd6da1c2f6c6a4f2aedf68836f37085e12b"],"state_sha256":"f1f259cf4c12ea12d9a316e74a46c1d03f6ab9b1134df74d2d9de5e6f70168d6"}
