Grand Unification Theories

Fig. 4.1. Schematic thermal history of the Universe showing some of the major episodes envisaged in the standard model. GUTs is short for grand unification theories and MWB is short for (the last scattering of) the microwave background radiation. The Universe is dominated by radiation and relativistic particles up to a time a little before that of MWB and by matter (including non-baryonic matter) thereafter, with dark energy eventually taking over.

The imification of fundamental forces, respectively of the first three types of the interactions from the Nature generates the so-called GUT (Grand Unification Theory), which when extended to the fourth interaction - the gravitational one (see Figure 1.5) constitutes the TOE (Theory of... [Pg.44]
