Grand Unified Theories predict baryon instability and, for most of the models, the proton decay widths are the only quantities potentially measurable in experiments. However, the calculations of proton lifetime usually involve severe theoretical uncertainties due to, e.g., perturbative techniques employed or difficulties in estimating the large-scale threshold effects. Similarly, the proximity...

We present an example of an extension of the Standard Model where unification of strong and electroweak interactions occurs at a level comparable to that occurring in the minimal supersymmetric standard model. The key feature of this model is that, besides the elementary particles of the SM a new set of particles subject to a superstrong interaction at the scale of few TeV, is present and...

In this communication we will show how M Theory compactified on G2 manifolds provide all the ingredients for model building and a yet-much-unexplored territory. In doing so we will present the so-called G2-MSSM, an SU(5) class of models with the MSSM spectrum, before presenting the most recent developments on SO(10) SUSY GUTs arising from M Theory on G2 manifolds. We will show that SO(10) SUSY...

To take advantage of the expected sensitivity increase in the next generation experiments searching for proton decay (Hyper-K, DUNE, ...), the precision of proton lifetime predictions has to improve significantly, which implies the need to go to the next-to-leading order calculation. That means considering the 2-loop running of all the couplings with the use of the 1-loop threshold effects...

Motivated by some string theory considerations the classical 4-dimensional spacetime may actually be quantum and exhibit a canonical non-commutative structure. We used recent observation of gravitational waves by LIGO Collaboration to constraint the scale of spacetime noncommutativity.
