Bino-Higgsino Mixed Dark Matter in a Focus Point Gaugino Mediation

Abstract

We investigate the neutralino dark matter in the focus point gaugino mediation model with the O(100) GeV gravitino. The thermal relic abundance of the neutralino with a sizable Higgsino fraction can explain the dark matter density at the present universe. The spin-independent cross section is marginally consistent with the current upper limit from the XENON 100 experiment, and the whole parameter region can be covered at the XENON1T experiment. We also discuss the origin of the gluino mass to wino mass ratio at around 3/8, which is crucial for the mild fine-tuning in the electroweak symmetry breaking sector. It is shown that the existence of the non-anomalous discrete R-symmetry can fix this ratio to 3/8.
