Description

In this work, we present a solution of the experimental anomaly in $g-2$ for the $Z^\prime$ charges allowed by the anomaly equations and the constraints coming from the Yukawa Lagrangian terms.
The $Z^\prime$ considered here has a minimum fermion content, i.e., our models contain only the standard model fermions, 3 right-handed neutrinos, and one exotic charged lepton. The allowed parameter space for $g-2$ was obtained with a $68\%$ confidence level. The region allowed by neutrino trident production $m_{Z^\prime}/g_{Z^\prime} > 0.75$~TeV was also found. A mass of $80$~GeV was assumed for the exotic particle.
