(Grand Unified Theories)


We shall pass through the motivation for extending the SU(3)xSU(2)xU(1) gauge symmetry of the Standard Model of particle physics to a simple or semi-simple gauge group, which would eventually leave us with two basic classes of unified frameworks - the SU(5) grand unification and the left-right symmetric models involving namely the Pati-Salam and SO(10) scenarios. We shall discuss some of the consequences of embedding the Standard Model into such "unified" theories, be it unification of (some) gauge and Yukawa couplings at some very high scale, the consequences for baryon stability, and/or hints on fundamental parameters governing the neutrino physics. We shall also discuss the hierarchy problem and the role of supersymmetry in Grand unifications.
