Abstract

From the requirement of the absence of the Landau pole singularity for the effective top quark Yukawa coupling constant \( {{\bar h}_t} \) up to the Planck scale in SU(5) supersymmetric model we find for the top quark mass an upper bound mt ≤ 187 GeV. For the SU(5) fixed point solution, which can be interpreted as the case of composite superhiggses we find mt ≈ 183 GeV. From the requirement that the mb/mτ prediction of the supersymmetric SU(5) has been succesfull we find that 145 GeV ≥ mt ≥ 190 GeV.
