However, this calculation is currently limited by stochastic noise stemming from a light and charm quark loop GIM subtraction. The split-even approach is an alternative estimator for such loop differences, and has shown a large variance reduction in certain quantities. We present an investigation into the use of the split-even estimator in the calculation of the rare kaon decay.","authors_text":"Antonin Portelli, Raoul Hodgson, Ryan Hill, Vera G\\\"ulpers","cross_cats":["hep-ph"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"hep-lat","submitted_at":"2025-01-30T14:04:44Z","title":"Split-even approach to the rare kaon decay $K \\to \\pi \\ell^+ \\ell^-$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2501.18358","kind":"arxiv","version":1},"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":"sha256:5eb2b244ad78df7911f2f42500c1a30640393d1874bd72dfc94b0a32c3c87629","target":"record","created_at":"2026-07-05T10:07:33Z","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":"3307e48f19e0accf9e2ff0df228abd33f328dc8c8058626e7395c74201e3dd4d","cross_cats_sorted":["hep-ph"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"hep-lat","submitted_at":"2025-01-30T14:04:44Z","title_canon_sha256":"8787de4cc025e7b7424a33b53741fafb9d57383721b955c2013cdff1500571ca"},"schema_version":"1.0","source":{"id":"2501.18358","kind":"arxiv","version":1}},"canonical_sha256":"2cfcbd0bd8b3a9826447ede46a438c82b8c338d9ac623eea0d051fd6f6874e32","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2cfcbd0bd8b3a9826447ede46a438c82b8c338d9ac623eea0d051fd6f6874e32","first_computed_at":"2026-07-05T10:07:33.193814Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:07:33.193814Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Mqo9PP96R6dz7J7QusK3vUHW+UV9FmBfOupmQwL/XfUnpHl395irW7anyZUIDPzaTweMMFxNSpoEpDCmpG1cDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:07:33.194311Z","signed_message":"canonical_sha256_bytes"},"source_id":"2501.18358","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5eb2b244ad78df7911f2f42500c1a30640393d1874bd72dfc94b0a32c3c87629","sha256:473464655c50eba755c1a043bba79022b4082e8e0e61839d9a08adb8ce2f9d4a"],"state_sha256":"8a004ffb0efc47e5654627d4e7db4d338090a679e1e61035b890a2bcf68589be"}
