Understand

We study effects of multiple scalar fields (scalar isocurvatons) with the Hubble scale masses on the inflationary bispectrum in the squeezed limit, particular paying attention to the question how to disentangle mass spectra of such fields.

We consider two isocurvatons with almost degenerate masses and the coupling of an inflaton to both isocurvatons as an example.
We find that the characteristic feature associated with nearly degenerate masses appears in the oscillating part of the bispectrum, which is dominated by a waveform with a specific wavelength roughly given by an inverse of the mass difference.
Such a waveform with a relatively longer wavelength can be easily identified and useful for disentangling almost degenerate mass spectra.
