For minimal -supersymmetry, the theory stays perturbative to the GUT scale for . This upper bound is relaxed when one either takes the criterion that all couplings are close to 4 for non-perturbation or one allows for new fields at the intermediate scale between the weak and GUT scale. We show that a hidden gauge sector with spontaneously broken scale 10 TeV improves this bound as instead. This may induce significant effects on the Higgs physics, such as decreasing fine tuning involving the Higgs scalar mass, as well as on the small -phenomenology.
