The Standard Model (SM) of particle physics, based on the gauge group SU(3)c ⊗ SU(2)L ⊗ U(1)Y accounts for the basic constituents of matter, in three generations of quarks, three generations of leptons and the gauge bosons. Despite providing a successful explanation of the fundamental particles and their interactions to a remarkable level of precision, the SM suffers from few shortcomings which urge us to look for physics beyond the SM (BSM). Amongst the various BSM approaches proposed over the last few decades, the ones based upon Grand Unified Theories (GUTs) have turned out to be quite noteworthy. Numerous models based upon GUTs such as SU(5), SU(6), E6, SO(10) etc. have been discussed in literature, however ideas based on SU(5) continue to be especially interesting. This can be attributed to the fact that SU(5) being the prototype GUT incorporates all the essential features of grand unification without the need of complicated algebra. In the present paper, beginning with the urge to look for grand unified theories, we intend to lay out the fundamentals of SU(5) GUT. Particular emphasis would be laid on its theoretical framework and generation of fermion masses in it. Shortcomings of SU(5) and a roadmap to more ambitious theories would also be sketched.
