Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

We make explicit the statement that the minimal supersymmetric (SUSY) SU (5) model has
been excluded by the SuperKamiokande search for the process p→ K+ ν. This exclusion is …

In models of baryogenesis based on grand unified theories (GUTs), the baryon asymmetry of
the Universe is generated through the CP and baryon number violating, out-of-equilibrium …

A bstract We propose a renormalisable model based on A 4 family symmetry with an SU (5)
grand unified theory (GUT) which leads to the minimal supersymmetric standard model …

We discuss the proton decay problem in theories with low gravity and/or GUT scales. We
pointed out that the gravity induced proton decay can be indeed suppressed up to a desired …

We calculate the high and low scale threshold corrections to the D= 6 proton decay mode in
supersymmetric SU (5) grand unified theories with higher-dimensional representation Higgs …

Potentially large nonuniversal corrections to the soft supersymmetry-breaking parameters
arise from their evolution between the Planck and the grand-unification scales. We detail …

A bstract We analyze nucleon decay modes in a no-scale supersymmetric flipped SU (5)
GUT model, and contrast them with the predictions for proton decays via dimension-6 …

Motivated by the large mixing angle solutions for the atmospheric and solar neutrino
anomalies, flavor changing neutral current processes and lepton flavor violating processes …

Proton decay is a major prediction of grand-unified theories (GUT) and its observation would
indicate baryon number violation that is required for baryogenesis. Many decades of …
