Description
The minimal renormalizable supersymmetric SU(5) GUT model has long been proclaimed ruled out on the account of colour Higgs triplet being either too heavy to allow for the gauge coupling unification or too light to satisfy the proton decay bounds. We have managed to prove that for large trilinear supersymmetry breaking terms and only a slightly heavier superpartner spectrum the perturbative model is still alive and can be reconciled with all phenomenological constraints from accommodating the measured Higgs boson mass and the correct mass relations among light fermions at the low scale to proton decay bounds, vacuum metastability and unification.
