Higgs Mass Prediction with Non-universal Soft Supersymmetry Breaking in MSSM

Abstract

In the framework of the MSSM the non-universal boundary conditions of soft SUSY breaking parameters are considered. Taking as input the top, bottom and Z-boson masses, the values of the gauge couplings at the EW scale and the infrared quasi-fixed points for Yukawa couplings and the soft parameters the mass of the lightest CP-even Higgs boson is found to be m_h=92.7^{+10}_{-4.9} +- 5 +- 0.4 GeV/c^2 for the low \tanβcase and m_h=125.7^{+6.4}_{-9.0} +- 5 +- 0.4 GeV/c^2 (μ> 0) or m_h =125.4^{+6.6}_{-9.0} +-5 +- 0.4 GeV/c^2 (μ< 0) in the case of large $\tanβ$.
