The calculation is performed close to the physical pion mass (m_pi = 142.9(1.1) MeV and with a single lattice spacing (a^-1= 1.375(9) GeV.) We find Re(A_2) = (1.436 \\pm 0.063_{stat} \\pm 0.258_{syst}) times 10^-8 GeV and Im(A_2) = (-6.29 \\pm 0.46_{stat} \\pm 1.20_{syst})\\times 10^{-13} GeV. These results are combined with the experimental result for epsilon'/epsilon"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1111.4889","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"}
