We found a positive intercept for the spin-flip generalized transverse momentum-dependent parton distribution (GTMDs) ${\\rm Re}(F_{1,2})$ as, \\begin{eqnarray} {\\rm Re}(F_{1,2}) \\sim \\left(\\frac{1}{x}\\right)^{{\\bar \\alpha}_s\\left(4\\ln2-8/3\\right)} \\left(\\cos 3\\phi_{k\\Delta} +\\cos \\phi_{k\\Delta}\\right). \\nonumber \\end{eqnarray} This is done by analytically solving the integro-differential evolution equation for ${\\rm Re}(F_{1,2})$, recently proposed by Hatta and Zhou, in the "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2312.04132","kind":"arxiv","version":3},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2312.04132/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"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"}
