YANG-MILLS THEORY 1. Introduction In 1954, Yang and Mills
... There are several other interesting Yang-Mills theories. For example, it has been suggested that the standard model, based on the group SU (3) × SU (2) × U (1), is a subgroup of a larger simple group, such as SU (5). Theories of this kind, which attempt to unify interactions are sometimes known as g ...
