The coupling strength between the charm quarks and the QGP constituents, quantified by the spatial diffusion coefficient $2\\pi TD_{s}$, is obtained by performing a phenomenological fit analysis to the lattice QCD calculations, resulting in $2\\pi TD_{s}=const.$ (\\textbf{Model-A}) and $2\\pi TD_{s}=1.3 + (T/T_{c})^2$ (\\textbf{Model-B}). We find that the relative azimuthal distribution of the initially back-to-back generated $c\\bar{c}$ pairs presents a broadening behaviour, which is more pronoun"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.01508","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"}
