NMSSM with generalized deflected mirage mediation

We propose to generate a realistic soft SUSY breaking spectrum for Next-to-Minimal Supersymmetric Standard Model (NMSSM) with a generalized deflected mirage mediation scenario, in which additional Yukawa and gauge mediation contributions are included to deflect the renormalization group equation trajectory. Based on the Wilsonian effective action obtained by integrating out the messengers, the NMSSM soft SUSY breaking spectrum can be given analytically at the messenger scale. We find that additional contributions to m${}_S^2$ can possibly ameliorate the stringent constraints from the electroweak symmetry breaking and 125 GeV Higgs mass. Constraints from dark matter and fine-tuning are also discussed. The Barbieri–Giudice fine-tuning measure and electroweak fine-tuning measure in our scenario can be as low as O(1), which possibly indicates that our scenario is natural.
