Abstract:
We investigate the possibility to realize the unification of the Standard
Model gauge interactions at the low scale in four dimensions. We find that the
fields needed to define a minimal theory where baryon and lepton numbers are
local symmetries, allow for unification at the low scale in agreement with
experiments. In these scenarios the proton is stable and we briefly discuss the
implications for cosmology.
