Abstract

We propose a solution to the recent W mass measurement by embedding the Standard Model within E₆ models. The presence of a new U(1) group shifts the W boson mass at the tree level and introduces a new gauge boson Z' which has been searched for at collider experiments. In this article, we identify the parameter space that explains the new W mass measurement and is consistent with current experimental Z' searches. As U(1) extensions can be accommodated in supersymmetric models, we also consider the supersymmetric scenario of E₆ models, and show that a 125 GeV Higgs may be easily achieved in such settings.
