ISR enhances cross section $\\sigma(e^-e^+\\to\\jpsi+gg+X)$ by about $15-25\\%$, which is almost the same size as the QCD and relativistic correction. Moreover, ISR slightly changes $\\sigma(e^-e^+\\to\\jpsi+c\\bar{c}+X)$. The $\\jpsi$ momentum spectrum in $e^-e^+\\to\\jpsi+gg+X$ and in $e^-e^+\\to\\jpsi+c\\bar{c}+X$ is softer after the photon showering from the initial $e^{\\pm}$ beam radiation. After combining the QCD,relativistic, and ISR corrections,a more precise t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.5840","kind":"arxiv","version":2},"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"}
