Dirac gamma-equation, classical gauge fields and Clifford algebra

Abstract

An equation, we call Dirac gamma-equation, is introduced with the help of the mathematical tools connected with the Clifford algebra. This equation can be considered as a generalization of the Dirac equation for the electron. Some features of Dirac gamma- equation are investigated (plane waves, currents, canonical forms). Furthermore, on the basis of local gauge invariance regarding unitary group, a system of equations is introduced consisting of Dirac gamma-equation and the Yang-Mills or Maxwell equations. This system of equations describes a Dirac's field interacting with the Yang-Mills or Maxwell gauge field. Characteristics of this system of equations are studied for various gauge groups and the liaison between the new and the standard constructions of classical gauge fields is discussed.
