Matter bispectrum in cubic Galileon cosmologies
  In this paper we obtain the bispectrum of dark matter density perturbations
in the frame of covariant cubic Galileon theories. This result is obtained by
means of a semi-analytic approach to second-order perturbations in Galileon
cosmologies, assuming Gaussian initial conditions. In particular, we show that,
even in the presence of large deviations of the linear growth-rate w.r.t. the
{\Lambda}CDM one, at the bispectrum level such deviations are reduced to a few
percent.
