The relation between QCD and valence quark model,\n  2. The evaluation of the nonlocal condensate $ \\la \\bar{q}(x)q(0)\\ra $, its relation to heavy-light $\\bar{q}Q$ quark system and to constituent quark mass,\n  3. The asymptotic behavior of the nonperturbative pion wave function $\\psi(\\k, x)$ at $x\\rightarrow 0,~1, \\k \\rightarrow \\infty$ and\n  4. The large order behavior of perturbative series.\n  The analysis is based on such general methods as dispersion relations, duality and PCAC. We use the steepest descent"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/9410228","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"}
