Implications of CDF $W$-mass and $(g-2)_\mu$ on $U(1)_{L_\mu-L_\tau}$ model

Abstract

We study the implications of the recent anomalies in the $W$-boson mass and the anomalous magnetic moment of the muon on $U(1)_{L_\mu-L_\tau}$ model. We show that the introduction of vector-like leptons which mix with muon can solve both anomalies. Contrary to the conventional wisdom the electroweak scale $Z'$-boson is allowed without conflict with the trident neutrino production experiments.
