This can drive a \"strange-beauty\" squark ($\\widetilde{sb}_{1}$) to be rather light, but still evade the $b\\to s\\gamma$ constraint. Low energy constraints imply that all other superpartners are at TeV scale, except for a possibly light neutralino, $\\widetilde \\chi_1^0$. Whether light or heavy, the $\\widetilde{sb}_{1}$ can impact on the $B_s$ system: $\\Delta m_{B_s}$ and indirect CP phase, even for $B_s \\to \\phi\\gamma$. Direct search is similar to usual $\\tilde b \\to b\\widetilde \\chi_1^0$, but existing bounds are weake"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0103094","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":""},"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"}
