In this mechanism, $B$-mesons decay into a Standard Model baryon and a dark-sector antibaryon, denoted by $\\psi_{DS}$. Within this scenario, we investigate the allowed mass window for $\\psi_{DS}$ using Light Cone Sum Rules (LCSR) for $B_d\\rightarrow\\Lambda \\, \\psi_{DS}$ decay. To include non-perturbative effects, we employ contributions up to twist-6 of the $\\Lambda$ distribution amplitudes in the operator product expansio"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"We derive the branching fraction as a function of dark antibaryon mass and, by comparing with the experimental limits by the BaBar and Belle collaborations, determine the mass ranges of ψ_DS consistent with the B-mesogenesis mechanism.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the light-cone OPE truncated at twist-6 of the Λ distribution amplitudes is sufficient to accurately capture the non-perturbative QCD effects for this decay channel without significant higher-twist corrections.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"The mass ranges for the dark antibaryon ψ_DS are determined by deriving the B_d → Λ ψ_DS branching fraction via light-cone QCD sum rules and comparing it to BaBar and Belle experimental bounds.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"The branching fraction of B_d to Lambda plus dark antibaryon constrains the mass of the dark antibaryon in B-mesogenesis.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"837f8f845db4438dee50e8e9bf4d27a3b51728081664b47f4e2f791cf1675380"},"source":{"id":"2605.13701","kind":"arxiv","version":1},"verdict":{"id":"4803307d-8fd2-4813-84b1-ba029ff89d24","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-14T17:44:58.026463Z","strongest_claim":"We derive the branching fraction as a function of dark antibaryon mass and, by comparing with the experimental limits by the BaBar and Belle collaborations, determine the mass ranges of ψ_DS consistent with the B-mesogenesis mechanism.","one_line_summary":"The mass ranges for the dark antibaryon ψ_DS are determined by deriving the B_d → Λ ψ_DS branching fraction via light-cone QCD sum rules and comparing it to BaBar and Belle experimental bounds.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the light-cone OPE truncated at twist-6 of the Λ distribution amplitudes is sufficient to accurately capture the non-perturbative QCD effects for this decay channel without significant higher-twist corrections.","pith_extraction_headline":"The branching fraction of B_d to Lambda plus dark antibaryon constrains the mass of the dark antibaryon in B-mesogenesis."},"references":{"count":78,"sample":[{"doi":"","year":null,"title":"+m 2(1−2x 04x3 0)−s 0(1 +x 0)2 ! +M 2m2 Λx3 0 I2 3(x0) +I 3(x0)(1 +x 0) h s0(1−x 0) +m 2 Λ(−1 + 4x0 +x 2 0) i +m 2 Λx0 h s0(1 +x 0)2 +m 2 Λ(−1−2x 0 + 4x2 0 + 4x3 0) i! +M 2I1x0 −I 2 3(x0)(1 + 2x0)−I 3","work_id":"0f8f76ba-3b3d-4572-b654-66e5eb295e13","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":null,"title":"(C2) 14 The corresponding correlation functions for model(b)enter the LCSR calculation in an analogous way","work_id":"a8b3f446-eb75-42fe-8441-fb9fe2222ff1","ref_index":2,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2016,"title":"Planck 2015 results.
