Pecci-Quinn Extension of the Natural Hybrid Inflation Model

다국어 초록 (Multilingual Abstract)

The "natural hybrid inflation model," which combines the supersymmetric hybrid model and the natural inflation model, was proposed to achieve the spectral index of 0.96, and an axion decay constant of intermediate scale. By introducing both the U(1)_R and a shift symmetry and employing the minimal Kahler potential, we were able to avoid the eta-problem. The two inflaton fields in this model can admit a large non-Gaussianity. For a full realization of the idea of the natural inflation, the shift symmetry in the model should be embedded in a U(1)_(PQ) symmetry.
