Description

We consider a simple mechanism in a supersymmetric GUT with an extra reverse doublet-triplet splitting near the GUT scale, where the mass of an extra doublet is greater than the mass of an extra triplet by a few orders of magnitude. This extra splitting can lower the prediction of αs via threshold corrections and make it consistent with the values being suggested by various low energy measurements. As an example we implement this mechanism in a supersymmetric SO(10) GUT with a built-in Dimopoulos-Wilczek mechanism of doublet-triplet splitting as well as a mechanism to suppress the Higgsino mediated proton decay strongly.
