Computational Determination of the Dirac-Theory Adjunctator

Abstract EN

A number of particle properties stem from the use of γ0 as adjunctator (Bargmann-Pauli) in the Dirac theory (spin alignment, Dirac current, etc.).

The early motivations for accepting γ0 as adjunctator were representation-dependent, mildly bearing relation to the actual conditions forcing γ0 as adjunctator.

Representation-independent approaches to the physical predictions of the Dirac equation are somewhat new, here presented as being the reasons for γ0 as adjunctator of the Dirac theory, together with the essential role of the latter in the physical aspects of the theory.
