We include both direct color-singlet production ($gg \\to J/\\psi$g) as well as a feed-down from $\\chi_{c} \\to J/\\psi \\gamma$ and $\\psi' \\to J/\\psi X$. The production of the decaying mesons ($\\chi_{c}$ or $\\psi'$)is also calculated within NRQCD $k_{t}$-factorization. The corresponding matrix elements for $gg \\to J/\\psi$, $gg \\to \\psi'$ and $gg \\to \\chi_{c}$ include parameters of the nonre"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1609.08413","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":""},"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"}
