A wire-by-wire tracking efficiency diagnostic is presented for the Belle~II Central Drift Chamber~(CDC). The method is directly analogous to the extrapolation-based efficiency measurement standard in resistive-plate-chamber~(RPC) stacks developed for the India-based Neutrino Observatory~(INO). A reference track (helix) is extrapolated to each wire layer; the fraction of crossings that contain an associated hit defines the per-wire efficie"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"the method reveals localised tracking failures that are invisible to conventional channel-level diagnostics","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"A reference track helix can be extrapolated accurately to each wire layer and hits can be associated without significant bias from the tracking algorithm or reconstruction","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"A new diagnostic creates per-wire efficiency plots for the Belle II CDC by extrapolating helix reference tracks and measuring the fraction of expected crossings with associated hits.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Wire-by-wire efficiency plots reveal localized tracking failures in the Belle II Central Drift Chamber","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"83c7d63b4a34851e4d76f9f7b3192a26c7e8ca5efad9bdf69815c8da7a4c31b0"},"source":{"id":"2605.17381","kind":"arxiv","version":1},"verdict":{"id":"a19a999b-bbe0-46fc-804e-25219a1d0e5b","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T22:47:01.883516Z","strongest_claim":"the method reveals localised tracking failures that are invisible to conventional channel-level diagnostics","one_line_summary":"A new diagnostic creates per-wire efficiency plots for the Belle II CDC by extrapolating helix reference tracks and measuring the fraction of expected crossings with associated hits.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"A reference track helix can be extrapolated accurately to each wire layer and hits can be associated without significant bias from the tracking algorithm or reconstruction","pith_extraction_headline":"Wire-by-wire efficiency plots reveal localized tracking failures in the Belle II Central Drift Chamber"},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2605.17381/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"doi_title_agreement","ran_at":"2026-05-19T23:01:19.664230Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_compliance","ran_at":"2026-05-19T22:52:14.231450Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"claim_evidence","ran_at":"2026-05-19T21:41:57.769844Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"ai_meta_artifact","ran_at":"2026-05-19T21:33:23.708157Z","status":"skipped","version":"1.0.0","findings_count":0}],"snapshot_sha256":"b811f29a8e4fd1dea0c0b92dfd898816df6ce0b121b90b1be5c5323832eee2c4"},"references":{"count":5,"sample":[{"doi":"","year":2010,"title":"Belle II Technical Design Report","work_id":"38bf24e4-47aa-44bf-b40a-cb948729620f","ref_index":1,"cited_arxiv_id":"1011.0352","is_internal_anchor":true},{"doi":"10.1016/j.cpc.2020.107610","year":2021,"title":"Track finding at Belle II","work_id":"41a214cc-e585-4478-9c57-d21bf9d38d8c","ref_index":2,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"10.1007/s12043-017-1373-4","year":2017,"title":"Physics potential of the ICAL detector at the India-based Neutrino Observatory: a comprehensive study","work_id":"647567f8-732f-4162-a0b3-183a6940e15e","ref_index":3,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"10.1007/s41781-018-0017-9","year":2019,"title":"The Belle II core software","work_id":"1d22f48d-cb87-4776-b370-210f367ad153","ref_index":4,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"10.1088/1748-0221/14/04/p04009","year":2019,"title":"Leak Test of Resistive Plate Chamber Gap by Monitoring Absolute Pressure","work_id":"449817f6-68de-499f-9eb3-5f3ab408d4ad","ref_index":5,"cited_arxiv_id":"1812.00277","is_internal_anchor":true}],"resolved_work":5,"snapshot_sha256":"6e314337095a7e19def82628074eab77a404980ea54aba147db4014f1135f7f6","internal_anchors":2},"formal_canon":{"evidence_count":2,"snapshot_sha256":"b3de4bba2240d45eb3f30095d550c1e97104aced73eab00c4337417aad209aef"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
