Abstract

We propose a generalized form of the Thomas-Bargmann-Michel-Telegdi equations. These are first-order in both electric and magnetic fields and retain the conventional conserved quantities and constraints. Within this novel phenomenological framework, we delve into an archetypal measurement scenario. Specifically, we scrutinize the contributions to the standard definition of the anomalous magnetic moment observable, highlighting each new correction term.
