A Compatibility Check: Low-Scale Chiral U(1)X Theories Vs. (g-2)e Anomaly
Bibhabasu De
Abstract
Chiral Abelian extensions of the Standard Model (SM) gauge group may offer significant new possibilities for explaining various Beyond the Standard Model (BSM) phenomena within a common framework. The models being less explored in the literature only a few experimental constraints have been reported to date, leaving a major portion of the parameter space available for the New Physics (NP) phenomenology. The present paper considers three anomaly-free chiral Abelian extensions and examines the compatibility of the corresponding low-scale parameter spaces with the observed (g-2)e anomaly. The analysis results in stringent exclusion limits, completely ruling out the considered chiral models when used in complementarity with the existing experimental bounds.
