Implications of this mixing for decays of $\\ppp$ to non-charmed final states are discussed. (i) The ratio $\\Gamma(\\ppp \\to \\gamma + \\chi_{c2})/ \\Gamma(\\ppp \\to \\gamma + \\chi_{c0})$ is expected to be highly suppressed if $\\ppp$ is a pure D-wave state, and is enchanced by mixing. (ii) The expected decay $\\pp \\to \\rho \\pi$ and other ``missing'' modes can appear as corresponding $\\ppp$ partial widths, enhanced by a f"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0105327","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"}
