We show that this hypothesis can be tested with a PBq (ten kilocurie scale) 144Ce or 106Ru antineutrino beta-source deployed at the center of a large low background liquid scintillator detector. In particular, the compact size of such a source could yield an energy-dependent oscillating pattern in event spatial distribution that would unabiguously determine neutrino mass differences and mixing angles.","authors_text":"Alain Letourneau, Davide Franco, David Lhuillier, Guillaume Mention, Maximilien Fechner, Michel Cribier, Stefan Schoenert, Thierry Lasserre, Vasily Kornoukhov","cross_cats":["nucl-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ex","submitted_at":"2011-07-12T16:20:37Z","title":"A proposed search for a fourth neutrino with a PBq antineutrino source"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1107.2335","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":"sha256:5c7c40164e538882c94d43117607a739d19ecd319a03c91426b95fd4215fd6f1","target":"record","created_at":"2026-05-18T02:01:19Z","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":"b416b5882822e4532c2d19f9b3753f8b1e8ce8018f6cca6e55c5895052623dce","cross_cats_sorted":["nucl-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ex","submitted_at":"2011-07-12T16:20:37Z","title_canon_sha256":"90304ae505aad7aeffb20613f14a0002244c2ca8b5e181217e1a8389e8896e59"},"schema_version":"1.0","source":{"id":"1107.2335","kind":"arxiv","version":2}},"canonical_sha256":"f99b90145388fe891d86a1e92037d7b4b586f25925dd1300156055efb4e914a9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f99b90145388fe891d86a1e92037d7b4b586f25925dd1300156055efb4e914a9","first_computed_at":"2026-05-18T02:01:19.557860Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:01:19.557860Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"g+yJDwsNnXePpPY8K9QiGNCspqP3wJEk/bzXN2qBrFqf4RkpmIBOVMHPwk2tEOB6X0viqNyc7jmN5C0RTCjfAg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:01:19.558654Z","signed_message":"canonical_sha256_bytes"},"source_id":"1107.2335","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5c7c40164e538882c94d43117607a739d19ecd319a03c91426b95fd4215fd6f1","sha256:363e7d97b798668e79b984af12f8829990409ef014097b9e79777be19e4f6fb8"],"state_sha256":"1de3112471b7837d05c0cb9a580a4a3dd623aac4cb2b48dbbdb341657e956987"}
