In this Letter, we address this point for charged-current processes involving two pions -- pion $\\beta$ decay $\\pi^\\pm\\to\\pi^0 e^\\pm\\nu_e$ and hadronic $\\tau$ decays $\\tau^\\pm\\to\\pi^\\pm\\pi^0\\nu_\\tau$ -- whose decay rates depend on the so-called $\\gamma W$ box correction. Using recent results from lattice QCD, we show how to formulate the matching beyond leading-logarithmic accuracy, in particular, how to cancel the dependence on the scheme","authors_text":"Martin Hoferichter, Nicola Valori, Vincenzo Cirigliano","cross_cats":["hep-ex","hep-lat","nucl-ex","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2026-02-11T19:00:00Z","title":"Pion $\\beta$ decay and $\\tau\\to\\pi\\pi\\nu_\\tau$ beyond leading logarithms"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2602.11253","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":"sha256:3f44610cfb57cb95eb299e04bf4ae96f6275beaab9d037f48123b048298664be","target":"record","created_at":"2026-07-31T01:33:16Z","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":"bf19f54967e9efcaef1344c48f900bdfafcac282808db37541f1fd4fe7d2d2f9","cross_cats_sorted":["hep-ex","hep-lat","nucl-ex","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2026-02-11T19:00:00Z","title_canon_sha256":"a7ea9700cffd7cb95adb90cafdbcf851e8b6df3a9dd2638bca2b74d06412a890"},"schema_version":"1.0","source":{"id":"2602.11253","kind":"arxiv","version":2}},"canonical_sha256":"b4d47ed5a68821f5d989c52290ed1c8a7aa1682f07bd683fbf2603bb12e9f488","receipt":{"builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b4d47ed5a68821f5d989c52290ed1c8a7aa1682f07bd683fbf2603bb12e9f488","first_computed_at":"2026-07-31T01:33:16.024858Z","kind":"pith_receipt","last_reissued_at":"2026-07-31T01:33:16.024858Z","receipt_version":"0.3","signature_status":"unsigned_v0"},"source_id":"2602.11253","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3f44610cfb57cb95eb299e04bf4ae96f6275beaab9d037f48123b048298664be","sha256:23c5baadc8c215940c2e196bc8a9442106ac13a871b9b1078ee6e3c7c463d863"],"state_sha256":"c1a33cce9abc85c64840238af70fda6067ce90fdf2b802e585f6ba82d529b7bc"}
