“…As an example, we showed that lepton flavor violation in the SUSY seesaw mechanism could have order reduction. The cancellation also works with the anomaly mediation and it is interesting to introduce the seesaw mechanism or vectorlike fields in the TeV scale mirage mediation models [43][47, [66][67][68][69][70][71][72] without spoiling its little SUSY hierarchy. There might be a plethora of other phenomenological applications including massive gauge bosons as in the grand unified theories.…”

We study the modulus mediation of supersymmetry breaking motivated by superstring theory.We show that the renormalization group running of the soft supersymmetry breaking parameters due to the interactions of massive fields is canceled by the threshold corrections at one-loop order, if their mass is given by nonperturbative dynamics controlled by the same modulus that mediates supersymmetry breaking and a sum rule of the modular weights holds for the Yukawa couplings.As an example, we discuss order reduction of lepton flavor violation in the supersymmetric seesaw mechanism, which revives the parameter space already excluded.

“…In the minimal KKLT setup, α is a positive rational number [35,36]. In the literature, the phenomenology of positive α has been studied intensively particularly to resolve the fine-tuning problem to realize the electroweak (EW) symmetry breaking scale [40][41][42][43][44][45][46]. However, it is known that the muon g − 2 anomaly is hardly explained in the cases with positive α due to relatively heavy winos and bino.…”

The new measurement of the anomalous magnetic momentum of muon at the Fermilab Muon g − 2 experiment has strengthened the significance of the discrepancy between the standard model prediction and the experimental observation from the BNL measurement. If new physics responsible for the muon g − 2 anomaly is supersymmetric, one should consider how to obtain light electroweakinos and sleptons in a systematic way. The gauge coupling unification allows a robust prediction of the gaugino masses, indicating that the electroweakinos can be much lighter than the gluino if anomaly-mediated supersymmetry breaking is sizable. As naturally leading to mixed modulus-anomaly mediation, the KKLT scenario is of particular interest and is found capable of explaining the muon g − 2 anomaly in the parameter region where the lightest ordinary supersymmetric particle is a bino-like neutralino or slepton.
