Consistency of New CDF-II W Boson Mass with 123-Model

Abstract

Following the recent update measurement of the W boson mass performed by the CDF-II experiment at Fermilab which indicates $7\sigma$ deviation from the SM prediction. As a consequence, the open question is whether there are extensions of the SM that can carry such a remarkable deviation or what phenomenological repercussions this has. In this paper, we investigate what the theoretical constraints reveal about the \ott model. Also, we study the consistency of a CDF W boson mass measurement with the 123-model expectations, taking into account theoretical and experimental constraints. Both fit results of $S$ and $T$ parameters before and after $m_W^{\mathrm{CDF}}$ measurement are, moreover, considered in this study. Under these conditions, we found that the 123-model prediction is consistent with the measured $m_W^{\mathrm{CDF}}$ at a $95\%$ Confidence Level (CL).
