Phys. Rev. Lett. 100, 131804 (2008) [4 pages]Hypercharged Anomaly MediationReceived 27 November 2007; published 4 April 2008 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 α between the bino and gravitino mass lies in the range 0.05≲|α|≲0.25 and m3/2≳35 TeV. We summarize some of the experimental signatures of this scenario. © 2008 The American Physical Society URL:
