Abstract
We study the inflation dynamics of generalized dilaton–axion models with a new Fayet–Iliopoulos (FI) term, where both real and imaginary parts of the ‘dilaton–axion’ super-field evolve. We find that the turn rate per Hubble parameter is about
O
10
−
2
to
O
10
−
1
while the square of effective mass of entropic perturbation is about
O
10
−
1
. These results can be used for identifying the specific inflation pattern in the future observation.
