We evaluate Wigner functions for the $\\psi(2S)$ meson using both Gaussian and Coulomb wave functions, and investigate the wave function dependence in the $\\psi(2S)$ meson production by recombination of charm and anti-charm quarks. The enhanced transverse momentum distribution of $\\psi(2S)$ mesons compared to that of $J/\\psi$ mesons, originated from wave function distributions of the $\\psi(2S)$ and $J/\\psi$ meson in momentum space, provides a plausible explanation for the recent measurement of the nuclear modification factor"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1408.4756","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"}
