We study the chargino contributions to $Z$ penguin especially with the vacuum stability constraint. The vacuum decay rate is investigated, and it is shown that the discrepancy can be explained if superparticles are lighter than 4-6 TeV. Correlations with $\\mathcal{B}(K_L\\to\\pi^0\\nu\\bar\\nu)$ and other experimental constraints are also discussed.","authors_text":"Daiki Ueda, Kei Yamamoto, Motoi Endo, Satoshi Mishima","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2016-08-04T07:26:50Z","title":"Chargino contributions in light of recent $\\epsilon'/\\epsilon$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1608.01444","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":"sha256:6fb3e6184ecb91c49ad1bcb49041ff559e7e560d05422a9009d6fea7fa92c519","target":"record","created_at":"2026-05-18T01:01:53Z","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":"6cbc26b17477347214cec9b1e1d7ed1dd6550f40d0dd164c927e33294b9cebe3","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2016-08-04T07:26:50Z","title_canon_sha256":"4224a6a0e7f3055ad71e592b3502af2c826d8b812a9f5ec2ea08526c5d2bfdf6"},"schema_version":"1.0","source":{"id":"1608.01444","kind":"arxiv","version":1}},"canonical_sha256":"a86678a41dcc0f8fb413a186b7a879b9fa86dd45f13f39637717f5c469d1ce9a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a86678a41dcc0f8fb413a186b7a879b9fa86dd45f13f39637717f5c469d1ce9a","first_computed_at":"2026-05-18T01:01:53.100930Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:01:53.100930Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZsXGMltdJstaOO4kfJ9jru9m3ztfzu4XBNjZxqpQDb6GveEZF+uIxfWCpjOIvyWH6vhPH2JyhTGb21ZK3CYMAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:01:53.101449Z","signed_message":"canonical_sha256_bytes"},"source_id":"1608.01444","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6fb3e6184ecb91c49ad1bcb49041ff559e7e560d05422a9009d6fea7fa92c519","sha256:7cedc5df3cadc4f783974c80055ab3be3a10acda6800a4e61c65a3a6fb87358a"],"state_sha256":"06cf08c86059030a99fabafd4dc7d0e7deab03e82a2b70c16de135c9bde7f325"}
