The scalar-scalar-tensor inflationary three-point function in the axion
  monodromy model
  The axion monodromy model involves a canonical scalar field that is governed
by a linear potential with superimposed modulations. The modulations in the
potential are responsible for a resonant behavior which gives rise to
persisting oscillations in the scalar and, to a smaller extent, in the tensor
power spectra. Interestingly, such spectra have been shown to lead to an
improved fit to the cosmological data than the more conventional, nearly scale
invariant, primordial power spectra. The scalar bi-spectrum in the model too
exhibits continued modulations and the resonance is known to boost the
amplitude of the scalar non-Gaussianity parameter to rather large values. An
analytical expression for the scalar bi-spectrum had been arrived at earlier
which, in fact, has been used to compare the model with the cosmic microwave
background anisotropies at the level of three-point functions involving
scalars. In this work, with future applications in mind, we arrive at a similar
analytical template for the scalar-scalar-tensor cross-correlation. We also
analytically establish the consistency relation (in the squeezed limit) for
this three-point function. We conclude with a summary of the main results
obtained.
