Two possible solutions of the fourth generation CKM factor $(V^{*}_{\\acute{t}s}V_{\\acute{t}b})^(\\pm)$ are obtained as a function of the new $\\acute{t}$-quark mass $(m_{\\acute{t}})$ from the experimental results of the $B\\to X_{s}\\gamma$ together with the semileptonic decay $B\\to X_{c}\\ell\\bar{\\nu}$. The branching ratio of the decay $B\\to K^{*}\\nu\\bar{\\nu}$ in the two cases is estimated. In one case, a significant enhancement to the branching ratio of the decay"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0105116","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"}
