Three well established methods are used to extract the CP observables. The updated measurement of $\\gamma$ in the three-body $D^0$ Dalitz space results in $\\gamma = (57\\pm 16)^\\circ$. When combining the observables from all \\bdk studies, the best fit value for $\\gamma \\in [0,180]^\\circ$ is $\\gamma = 67.2^\\circ$ with $\\gamma \\in [55.1,79.1]^\\circ$ at 68%CL and $\\gamma \\in [43.9, 89.5]^\\circ$ at 95%CL. This represents the most precise $\\gamma$ values directly measured "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1307.7018","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"}
