The Higgs boson mass bound in MSSM broken at high scale

We study the dependence of the Higgs boson mass on the supersymmetry breaking scale in the minimal supersymmetric extension of the standard Weinberg-Salam model. In particular, we find that for supersymmetry breaking scale ${10}^8$ GeV $\le M_s\le {10}^{16}$ GeV and for $m_{top}^{pole}=175\pm 5$ GeV the Higgs boson mass is 120 GeV $\le m_h\le 160$ GeV
