The only subtlety comes from regularizing the functional integral over the pure spinor ghosts. In this paper, it is shown how to regularize this functional integral in a BRST-invariant manner, allowing the computation of arbitrary multiloop amplitudes. The regularization method simplifies for scattering amplitudes which contribute to ten-dimensional F-terms, i.e. terms in","authors_text":"Nathan Berkovits, Nikita Nekrasov","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2006-09-01T19:51:01Z","title":"Multiloop Superstring Amplitudes from Non-Minimal Pure Spinor Formalism"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0609012","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:f7009908829659e82bfc22b32edc1ec08160d03b4686ced5ca924bff5aca7a89","target":"record","created_at":"2026-07-04T17:02:04Z","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":"84476585ee020d20b30ab1242bff0bd8f42fca568c8f6518dfc7580c359634af","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"2006-09-01T19:51:01Z","title_canon_sha256":"50489238312aa46c02b3224ad38bf6540892c2cefa66be469f81657eeb0b7a42"},"schema_version":"1.0","source":{"id":"hep-th/0609012","kind":"arxiv","version":2}},"canonical_sha256":"164efcf30b247af07f71cd96a41342d22894afa230092c2ac6330d7b0f7d9a5b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"164efcf30b247af07f71cd96a41342d22894afa230092c2ac6330d7b0f7d9a5b","first_computed_at":"2026-07-04T17:02:04.201379Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:02:04.201379Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rcTynS02bt94m5sUCij+EZFOsR/gf5yg2kBSbxQpmiIy1Pt5ILd5RomV22Pf71vQYSbv7xxozb431bcvf3wdCA==","signature_status":"signed_v1","signed_at":"2026-07-04T17:02:04.201709Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0609012","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f7009908829659e82bfc22b32edc1ec08160d03b4686ced5ca924bff5aca7a89","sha256:85ef2ec8d5473ff5ccb7a38eb356baebebe132945e65698bd090d9bade86bf1e"],"state_sha256":"9ec57e155347ce609c72839e04a37d0a3f2256266b3350786ca6503166cdb6dc"}
