The dark sector consists of one fermion singlet $\\chi$ and one scalar singlet $\\chi$, which transforms as $\\chi\\to e^{i2\\pi/3}\\chi, \\phi\\to e^{i2\\pi/3}\\phi$ under the $Z_3$ symmetry. Regarding fermion singlet $\\chi$ as the dark matter candidate, the new interaction terms $y_\\chi \\phi \\bar{\\chi^c}\\chi$ and $\\mu\\phi^3/2$ could induce various new production channels. For instance, when $m_\\phi>2m_\\chi$, the pair decay $\\phi\\to\\chi\\chi$ could be the dominant channel, rather than the delayed decay $\\phi"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.12588","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2308.12588/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
