摘要Adopting the horizon-crossing approximation, we derive the spectral index of f(NL) in general N-flation model. Axion N-flation model is taken as a typical model for generating a large f(NL) which characterizes the size of local form bispectrum. We find that its tilt nf(NL) is negligibly small when all inflatons have the same potential, but a negative detectable nf(NL) can be achieved in the axion N-flation with different decay constants for different inflatons. The measurement of nf(NL) can be used to support or falsify the axion N-flation in the near future.
