For tiny interactions, the scalar is long-lived at detector scales and decays into displaced pairs of leptons or light mesons. We show that Belle II has a remarkable potential to probe scalars in the GeV range with couplings as small as $10^{-5}$. The predicted sensitivity is higher than at the long-baseline experiments FASER and NA62. We also investigate signatures of invisibly decaying scalars in rare meson decays with missing energy.","authors_text":"Anastasiia Filimonova, Ruth Sch\\\"afer, Susanne Westhoff","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2019-11-08T19:00:46Z","title":"Probing dark sectors with long-lived particles at BELLE II"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1911.03490","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:b82b7028d3e22d7db9b8127364cba0ce100dad29a7c942c079b56ad9c34dd442","target":"record","created_at":"2026-07-05T01:06:50Z","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":"9ff4111a549c245ac421b01fcda684f7e75a62df34cf35946be978a3e4f7102f","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2019-11-08T19:00:46Z","title_canon_sha256":"3efdbe9a938f87d533c7435b69e06fca963a987cedc2b8941ee7583787cb04f7"},"schema_version":"1.0","source":{"id":"1911.03490","kind":"arxiv","version":2}},"canonical_sha256":"702e770a6fcd2b83147ec4a16f51ecf16385459777126b7faf8716bba0f504cf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"702e770a6fcd2b83147ec4a16f51ecf16385459777126b7faf8716bba0f504cf","first_computed_at":"2026-07-05T01:06:50.839666Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:06:50.839666Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IPwv0DrxdecG1NmfMC/zu55X+3AOkB+7E6Mq8rfqafR4cpleR9QTcGkqId1UI116LFM5jnV846kNBtL/fticCg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:06:50.840154Z","signed_message":"canonical_sha256_bytes"},"source_id":"1911.03490","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b82b7028d3e22d7db9b8127364cba0ce100dad29a7c942c079b56ad9c34dd442","sha256:502752d41b54368b08d1ebd6978fa9eb449d8733f39def345beb49deac62fbde"],"state_sha256":"77a0256eab455de39932813603932fea636298c2d73e81b4abd280af6aa51f1c"}
