Smooth hybrid inflation with low reheat temperature and observable gravity waves in SU(5) × U(1)$_{χ}$ super-GUT
We realize smooth hybrid inflation in the framework of supersymmetric SU(5) × U(1)$_{χ}$ ⊂ SO(10) model which provides a natural solution to the monopole problem appearing in the spontaneous symmetry breaking of SU(5). The breaking of U(1)$_{χ}$ symmetry leaves a residual discrete Z $_{2}$ symmetry,...
