Such an interaction could accomodate $\\chi\\bar{\\chi}\\rightarrow\\gamma\\gamma$ processes which might be the cause of the observed feature in the FermiLAT spectrum, as well as $\\gamma^*/Z\\rightarrow \\gamma\\chi\\bar{\\chi}$ processes, which would predict excesses at the LHC in the $\\gamma+\\missET$ final-state. We reinterpret an ATLAS $\\gamma+\\missET$ analysis and the observed Fermi feature in the parameter space of our new effective theory to assess their consistency."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1307.5064","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"}
