Abstract
We explore the effects of three-loop minimal supersymmetric standard model
renormalisation group equation terms and some leading two-loopthreshold
corrections on gauge and Yukawa unification: each being one loop higher order
than current public spectrum calculators. We also explore the effect of the
higher order terms (often 2-3 GeV) on the lightest CP even Higgs mass
prediction. We illustrate our results in the constrained minimal supersymmetric
standard model. Neglecting threshold corrections at the grand unified scale,
the discrepancy between the unification scale
