Invariants for particle propagation in non-Abelian fields

Abstract

Characterising the propagation of particles in an external non-Abelian field only in terms of invariants constructed from its field tensor is not always sufficient, especially, in many analytically tractable and phenomenologically interesting cases.

“…(The computation involves solving the equation of motion for the probe in a classical background field, a widely used approach in this subject area [135][136][137][138][139][140][141][142][143][144][145][146][147][148], and a subsequent averaging over configurations.)
