Query: Grand Unification in High-scale Supersymmetry   A constraint on masses of superheavy gauge and Higgs multiplets at the grand
unification (GUT) scale is obtained from the gauge coupling unification in the
case of high-scale supersymmetry. We found that all of the particles may lie
around a scale of 10^16 GeV so that the threshold corrections to the gauge
coupling constants at the GUT scale are smaller than those in the case of the
low-energy supersymmetry. In addition, the GUT scale tends to be slightly lower
when the gauginos are heavier and, thus, the proton decay rate via the X-boson
exchange process is expected to be enhanced.
