I will discuss few minimal scalar extensions of the standard electroweak model that provide a simple setup for massive neutrinos in connection with an invisible axion. The presence of a chiral U(1) a la Peccei-Quinn drives the pattern of Majorana neutrino masses while providing a dynamical solution to the strong CP problem and an axion as a dark matter candidate. Such a renormalizable...

I will review the recent progress in the attempts to improve the accuracy of the existing proton lifetime estimates in the realm of the minimal non-supersymmetric SO(10) grand unified model and argue that a significant portion of its parameter space consistent with all existing constraints may be testable at the existing or near future experimental facilities.

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...

We explicitly show that the model with a Higgs breaking sector 27 + 27bar + 351' + 351'bar + 78 provides a realistic scenario for an E6 SUSY Grand Unified Theory. Although the 78 is not necessary for obtaining a Standard Model vacuum, doublet-triplet splitting cannot be performed in the simplified case, where the 78 is omitted. We study in detail the Yukawa sector of the model, where three...
