Title: Phenomenology of mixed modulus-anomaly mediation in fluxed string compactifications and brane models

Abstract

We examine low energy sparticle mass-spectrum and electroweak symmetry breaking in the mixed modulus-anomaly mediation which is naturally realized in KKLT flux compactification. We find that the anomaly-mediation effectively lowers messenger scale in the moduli-mediation and leads to 'squeezed' mass-spectrum distinct from any known mediation mechanisms. The lightest neutralino typically becomes a mixed state of bino and higgsino or pure higgsino, which has a considerable impact on the cold dark matter physics.
