Realistic Hybrid Inflation in 5D Orbifold SO(10) GUT

Abstract

We discuss the smooth hybrid inflation scenario in the context of a simple supersymmetric SO(10) GUT in 5D orbifold. In this GUT model, the SO(10) gauge symmetry is broken down to the Pati-Salam (PS) gauge group, SU(4)${}_c\times$ SU(2)${}_L\times$ SU(2)${}_R$, by orbifold boundary conditions and all matter and Higgs multiplets are placed only on the brane (PS brane) where only the PS symmetry is manifest. Further breaking of the Pati-Salam group to the Standard Model one is realized by VEVs of the Higgs multiplets $(4,1,2)\oplus (\overline{4},1,2)$. The gauge coupling unification is successfully realized at $M_{\mathrm{GUT}}=4.6\times 10^{17}$ GeV after incorporating the threshold corrections of the Kaluza-Klein modes, with the compactification scale (assumed to be the same as the PS symmetry breaking scale) $M_c=v_{\mathrm{PS}}=1.2\times 10^{16}$ GeV. We show that this orbifold GUT model can naturally leads us to the smooth hybrid inflation, which tunes out to be consistent with the WMAP 5-year data with the predicted $M_{\mathrm{GUT}}$ and $v_{PS}$ in the model.
