Gauge Theory and the Attempt at Grand Unification

  • Fayyazuddin

Abstract

Two fundamental questions continue to agitate our minds regarding: (a) the ultimate constituents of matter; and (b) the fundamental forces of nature. At our present state of knowledge the smallest known constituents of matter (as distinct from energy) can be divided into two classes: (i) leptons, and (ii) hadrons. Particles can only be classified according to the statistics which applies to them: (1) Fermi-Dirac statistics to particles with half-integral spin; and (2) Bose-Einstein statistics to particles with integral spin. Particles of the first type are called fermions and of the second type are called bosons.
