Theoretical bounds on the ``observable'', <m>_betabeta, are presented. By using experimental bounds on <m>_betabeta, allowed regions are obtained on the m_l-cos{2theta_12} plane, where m_l stands for the lightest neutrino mass. It is shown that Majorana neutrinos can be excluded by combining possible results of future neutrinoless double beta decay and {}^3H beta decay experiments. A possibility to constrain one of two Majorana phases is discussed also.","authors_text":"Hiroaki Sugiyama","cross_cats":[],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"2003-07-25T09:02:22Z","title":"Neutrinoless Double Beta Decay Constraints"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0307311","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":"sha256:0a0f297dc911429a6228d892ff1e9ecc0555b88ce72decba3cec573a16be8c9d","target":"record","created_at":"2026-05-18T00:36:56Z","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":"29c637ebc9c68e89e6eb13a1d365bf0daf8dd7cb26cd77017628d33bcffaaa49","cross_cats_sorted":[],"license":"","primary_cat":"hep-ph","submitted_at":"2003-07-25T09:02:22Z","title_canon_sha256":"af2a0a0d332695eed9b03310f0d1b874b0b484901d1e19c396275382c2bc98c0"},"schema_version":"1.0","source":{"id":"hep-ph/0307311","kind":"arxiv","version":1}},"canonical_sha256":"b79e3d706a4298d50e62389649662297fe52c185295686454f1d0fb9ceab421b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b79e3d706a4298d50e62389649662297fe52c185295686454f1d0fb9ceab421b","first_computed_at":"2026-05-18T00:36:56.471527Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:36:56.471527Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GfCTacwYSqMKEJ2toiEETukOBnB/0xP2iV5pxbSPpIDR7tQmc/4H+fSXUFcw1uMj/Cfp5dKm+BmczE7RTiUuBA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:36:56.472055Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/0307311","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0a0f297dc911429a6228d892ff1e9ecc0555b88ce72decba3cec573a16be8c9d","sha256:b0fc460b952402defd54cb26b2e2c2b11bf963f9d5575ce4e2ca69506365fe57"],"state_sha256":"a8860974fac4b4cfd01b503591579a4f756d4b89788d628c0892dc345f1dd28a"}
