$H \to b \bar{b}, \tau \bar{\tau}$ in Gauge-Higgs Unification

Abstract

We study the deviation of Higgs production through the gluon fusion process and the decay of Higgs boson to the bottom quark and the tau lepton in gauge-Higgs unification from the Standard Model prediction. We find that the signal strength of $gg \to H \to b\bar{b}, \tau\bar{\tau}$ is necessarily suppressed comparing to the SM predictions due to the dominant suppression of the Higgs production via gluon fusion.
