Abstract
We report that models of electroweak supersymmetry with gaugino mass unification and sequestered scalar masses can still produce viable spectra, as long as we include a set of non-standard supersymmetry breaking terms, which are trilinear in scalars like the A-terms, but are non-holomorphic in visible sector fields unlike the A- terms. These terms impart a subtle feature to one loop renormalisation group equations of soft supersymmetry breaking terms, indirectly sourcing flavor universal contributions to all scalar masses. These new contributions can even dominate over radiative corrections form bino, and help raise right handed sleptons above bino, while leaving a tell-tale signature in the spectrum.
Highlights
The complete absence of any genuine hint of new physics from the LHC, as well as null results in various direct and indirect searches for dark matter have put severe constraints on all models of electroweak (EW) supersymmetry

Summary
We report that models of electroweak supersymmetry with gaugino mass unification and sequestered scalar masses can still produce viable spectra, as long as we include a set of nonstandard supersymmetry breaking terms, which are trilinear in scalars like the A-terms, but are nonholomorphic in visible sector fields unlike the A- terms. Often using “locality” in setups with extra dimensions [1,2], or lattices of gauge groups connected by link fields [3,4], or even strong and nearly conformal dynamics of the hidden sector [5,6,7], these models sequester scalar masses at the input scale (say Λint), thereby ensuring that flavor universal gaugino mediation remains the sole source of scaler masses at infrared (IR) These elegant solutions to the flavor problem in supersymmetry [8] can solve the μ–Bμ problem [5], and provide a unique perspective to the fine-tuning problem [7], where dynamics brings in large cancellations in the Higgs mass matrix, while at the same time, accommodating gaugino mass unification.
