摘要: Abstract We propose an inflationary model (“natural hybrid model”), which combines the supersymmetric and natural inflation to achieve spectral index of 0.96, axion decay constant smaller than Planck scale, f ≪ M P . By introducing both U(1) R a shift symmetry employing minimal Kahler potential, eta-problem can be still avoided. The two inflaton fields in this admit large non-Gaussianity.
