Description
Recently an SO(11) gauge-Higgs grand unified theory (GHGUT) in 5D Randall-Sundrum warped space was proposed in PTEP(2015)111B01(arXiv:1504.03817). In this framework, the 4D SM bosons and fermions are naturally realized by the SO(11) bulk gauge boson and SO(11) spinor bulk fermions, respectively. GHGUT leads to gauge coupling unification, so it is inevitable to discuss the renormalization group evolution for SM gauge coupling constants because the value of the Weinberg angle from GUT prediction does not agree with its low-energy observation data. In this talk, I will discuss SM gauge coupling unification in the SO(11) GHGUT by using 4D renormalization group equations. This talk is based on PTEP(2016)043B02(arXiv:1512.05559).
