The calculation is performed on four ensembles of the 2+1-flavor domain-wall gauge configurations: $24^3 \\times 64$ ($a m_l= 0.005$, $a=0.114\\fm$) and $32^3 \\times 64$ ($a m_l = 0.004, 0.006, 0.008$, $a=0.085\\fm$). For pion masses close to $300\\MeV$ we find \\hbox{$\\Delta_{mix}=0.030(6)\\GeV^4$} at $a=0.114\\fm$ and $\\Delta_{mix}=0.033(12)\\GeV^4$ at $a=0.085\\fm$. The results are quite independent of the lattice spacing and they are significantly smaller than t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1204.6256","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"}
