Title: Hypercharged Anomaly Mediation

We show that, in string models with the minimal supersymmetric standard model residing on D-branes, the bino mass can be generated in a geometrically separated hidden sector. Hypercharge mediation thus naturally teams up with anomaly mediation. The mixed scenario predicts a distinctive yet viable superpartner spectrum, provided that the ratio {alpha} between the bino and gravitino mass lies in the range 0.05 < or approx. |{alpha}| < or approx. 0.25 and m{sub 3/2} > or approx. 35 TeV. We summarize some of the experimental signatures of this scenario.
