The inability to fix the sign of the bottom-quark Yukawa coupling from the available data plays a crucial role in accommodating a chiral fourth generation which is consistent with the bounds on the Higgs signal strengths. We show that effects of such a fourth generation can remain completely hidden not only in the production of the Higgs boson through gluon fusion but al","authors_text":"Anirban Kundu, Dipankar Das, Ipsita Saha","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-07-10T18:09:24Z","title":"Higgs data does not rule out a sequential fourth generation with an extended scalar sector"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1707.03000","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":"sha256:24d495105af463138d65abcbaef6f83ef280e6adc00ab73812ee9990c9320032","target":"record","created_at":"2026-05-18T00:25:18Z","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":"be144b82a7a908fad1c154559077878bac3049c100d6bfa813ddd9674ba44ac6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-07-10T18:09:24Z","title_canon_sha256":"445dda3052ba299436ad6929359fdc855aad99c78a04d8dd8432ee18e084b30e"},"schema_version":"1.0","source":{"id":"1707.03000","kind":"arxiv","version":2}},"canonical_sha256":"162ac84f3ed87d24ef83cf994bbded74d89e805737d7d8202be322254f7730c1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"162ac84f3ed87d24ef83cf994bbded74d89e805737d7d8202be322254f7730c1","first_computed_at":"2026-05-18T00:25:18.052537Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:25:18.052537Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tKPzMt98j/yqNzksReJtDNzljHFdOzpBXAu+hhlzzL2JpKLd7RYEaJsubLhGiW8trjzf//X4crmXzCqX4ZTpBA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:25:18.053169Z","signed_message":"canonical_sha256_bytes"},"source_id":"1707.03000","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:24d495105af463138d65abcbaef6f83ef280e6adc00ab73812ee9990c9320032","sha256:20940e5f2da83adc8db9bc68568ea95cb5b0034bfaadb4eb69a29379c6f8e6ad"],"state_sha256":"cb5e1f06395f590c74fbd422fc3e5b1b03b4295460b723e3393f89cc8acdc252"}
