We present simplified models that realize this fact by coupling a fermion dark sector to a two-Higgs doublet model. These models are generalizations of mixed bino-Higgsino dark matter in the MSSM, with more freedom in the couplings and scalar spectra. Annihilation near a pseudoscalar resonance allows a significant amount of parameter space for thermal relic dark matter compared to singlet-doublet dark matter, in which the fermions couple onl","authors_text":"Asher Berlin, Lian-Tao Wang, Stefania Gori, Tongyan Lin","cross_cats":["astro-ph.HE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2015-02-20T21:00:12Z","title":"Pseudoscalar Portal Dark Matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.06000","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":"sha256:6082852a5e5eb8063a68fa387b877d331cc0ca69d9173929dad88495f12603c4","target":"record","created_at":"2026-05-18T01:35:20Z","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":"66c739ec9f95f1b9a934e915c4bf9a5ad096535ce37da81443b9007ff18e3314","cross_cats_sorted":["astro-ph.HE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2015-02-20T21:00:12Z","title_canon_sha256":"38f6fa268c549d09c94866f2ea6b59feb0860fc63e4998bf73889f142bb7b78f"},"schema_version":"1.0","source":{"id":"1502.06000","kind":"arxiv","version":2}},"canonical_sha256":"01630e3f976644ccee766d990c316d0b3d65919c44712bec17a8d6cd6909424e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"01630e3f976644ccee766d990c316d0b3d65919c44712bec17a8d6cd6909424e","first_computed_at":"2026-05-18T01:35:20.398220Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:35:20.398220Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"i2foyXAfCOsmUnNvwR7tNfS81YN6GMDZHH2FLNFPKGXJ/ykk6SfdL1FDc2hCaGKBZLuKlzrHW/8ET7+Zjo2OBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:35:20.398819Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.06000","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6082852a5e5eb8063a68fa387b877d331cc0ca69d9173929dad88495f12603c4","sha256:4e2c74be3f628625586b500700f2b688b5f0ad3927a6e8ff79b97f6305491bec"],"state_sha256":"e95de58c441e8b8b97a889fa9d2cdaeeec328d56050c78c36c0c19026d4a23c2"}
