The Lagrangian still gives rise to second-order gravitational and scalar field equations, and thus offers a more generic class of single-field inflation than ever studied, with a richer phenomenology. We compute the power spectrum and the bispectrum, and clarify how the non-Gaussian amplitude depends upon parameters such as the sound speed. In so doing we try to keep as great generality as possible,","authors_text":"Jun'ichi Yokoyama, Masahide Yamaguchi, Tsutomu Kobayashi","cross_cats":["astro-ph.CO","gr-qc","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2011-03-09T09:24:13Z","title":"Primordial non-Gaussianity from G-inflation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1103.1740","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":"sha256:3a850b900f91f477e9720b36881aee6fe927710e664fd7a99554a7049fe29ad3","target":"record","created_at":"2026-05-18T04:20:37Z","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":"f768c529f01786945269e66b17e2f79153e7d414bee323b903974748fe2ab873","cross_cats_sorted":["astro-ph.CO","gr-qc","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2011-03-09T09:24:13Z","title_canon_sha256":"d6418adb0011c6be15069667b55308097411f19515b3a9eaa4c365ecfbe19317"},"schema_version":"1.0","source":{"id":"1103.1740","kind":"arxiv","version":2}},"canonical_sha256":"54ef36a99dc88bab27bdce1d5f7cd5714dc39701825ec5f7032169b09c7d95a9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"54ef36a99dc88bab27bdce1d5f7cd5714dc39701825ec5f7032169b09c7d95a9","first_computed_at":"2026-05-18T04:20:37.837884Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:20:37.837884Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XZy+o3GlZ9bgQgz69nxrizbO574K67nzF10JVF4ZupTRYAToIY8LB/i433SzL2+9F+8Om1LxSL6eNDKi0pn3BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:20:37.838597Z","signed_message":"canonical_sha256_bytes"},"source_id":"1103.1740","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3a850b900f91f477e9720b36881aee6fe927710e664fd7a99554a7049fe29ad3","sha256:99ea0cd9a45de4c0482879afe31d2c160a5133703abd467224c3a926acca3dcf"],"state_sha256":"4653690b08163a45db520d32c7a834575dca9c9e262fd7c1f9d0d7c437e4d416"}
