New Higgs Effects in B--Physics in Supersymmetry with General Flavour Mixing

John Foster, Ken-ichi Okumura, Leszek Roszkowski

We investigate the effect of general flavour mixing among squarks on the rare decays $\bar{B}\to X_s\gamma$, ${\bar{B}}_s\to {\mu }^{+}{\mu }^{-}$ and ${\bar{B}}_s-B_s$ mixing beyond the leading order in…
