Abstract
The CDF collaboration reported an anomaly of the W boson mass in 2022. We discuss the possibility to explain the anomaly in a gauge-Higgs unification model. We evaluate the W boson mass in the $SO(5) \times U(1)_X \times SU(3)_C$ gauge-Higgs unification in the Randall-Sundrum warped space. The muon decay proceeds by the exchange of not only the zero mode of the W boson but also Kaluza-Klein excited states at the tree level. We find that the anomaly can be explained by these effects in the gauge-Higgs unification model.
