講演内容
We study the properties of the dilaton gravity theory with the Gauss-Bonnet term. The black holes in such a model have always scalar hairs, and also have the minimum mass for the existance. We investigate the inflationary solutions for a specific type of the nonminimal coupling to the Gauss-Bonnet term and inflaton potential both analytically and numerically. We also calculate the observable quantities such as the power spectra of the scalar and tensor modes, the spectral indices, the tensor-to-scalar ratio, and the running spectral indices, and constrain our result with the observational data by Planck and BICEP2 experiment. The effects to the reheating will also be discussed.
