CP-safe Gravity Mediation and Muon g-2

Understand

We propose a CP-safe gravity mediation model, where the phases of the Higgs B parameter, scalar trilinear couplings and gaugino mass parameters are all aligned.

• Since all dangerous CP violating phases are suppressed, we are now safe to consider low-energy SUSY scenarios.
• As an application, we consider a gravity mediation model explaining the observed muon $g-2$ anomaly.
• The CP-safe property originates in two simple assumptions: SUSY breaking in the K\"ahler potential and a shift symmetry of a SUSY breaking field $Z$.
