One loop predictions of the finely tuned supersymmetric standard model

We study the finely tuned supersymmetric standard model, recently proposed by Arkani-Hamed and Dimopoulos, at the one loop level. The runnings of the four gaugino Yukawa couplings, the $\mu$ term, the gaugino masses, and the Higgs quartic coupling are computed. The Higgs mass is found to be 130–170 GeV for $M_s>{10}^6\mathrm{G}\mathrm{e}\mathrm{V}$. Measuring the Yukawa coupling constants at the 10% level can begin to constrain the supersymmetry breaking scale. Measuring the relationships between the couplings will provide a striking signal for this model.
