We point out in the case of $e^+e^-\\to TP$ transition due to charge conjugation invariance, only three channels are allowed: $e^+e^-\\to a_2^{\\pm} \\pi^\\mp$, $e^+e^-\\to K_2^{*\\pm} K^\\mp$ and the V-spin suppressed $e^+e^-\\to K_2^{*0} \\bar K^0+\\overline K_2^{*0} K^0 $. Cross sections of $e^+e^-\\to VP$ and $e^+e^-\\to TP$ at $\\sqrt{s}=3.67$ GeV and $\\sqrt{s}=10.58$ GeV are calculated and t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.09718","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"}
