Gauge hierarchy and SUSY: Think again

Abstract

We revisit the gauge hierarchy problem with the emphasis on the chiral property of the Standard Model. We present a model realizing a gauge hierarchy. Along this line, we also comment briefly on the "very light" axions and the upper bound on ${\theta }_{\mathrm{QCD}}$.
