Query: The CMB bispectrum from bouncing cosmologies   In this paper we compute the CMB bispectrum for bouncing models motivated by
Loop Quantum Cosmology. Despite the fact that the primordial bispectrum of
these models is decaying exponentially above a large pivot scale, we find that
the cumulative signal-to-noise ratio of the bispectrum induced in the CMB from
scales $\ell < 30$ is larger than $10$ in all cases of interest and therefore
can, in principle, be detected in the Planck data.
