Book Synopsis Constraints on Light Bottom Squarks from Radiative B-Meson Decays by :
Book excerpt: The presence of a light {tilde b} squark (m{sub {tilde b}} ≈ 4 GeV) and gluino (m{sub {tilde g}} ≈ 15 GeV) might explain the observed excess in b-quark production at the Tevatron. Though provocative, this model is not excluded by present data. The light supersymmetric particles can induce large flavor-changing effects in radiative decays of B mesons. We analyze the decays B → X{sub s}[gamma] and B → X{sub sg} in this scenario and derive restrictive bounds on the flavor-changing quark-squark-gluino couplings.
