A Perturbative Approach to the Redshift Space Power Spectrum: Beyond the
  Standard Model
  We develop a code to produce the power spectrum in redshift space based on
standard perturbation theory (SPT) at 1-loop order. The code can be applied to
a wide range of modified gravity and dark energy models using a recently
proposed numerical method by A.Taruya. This includes Horndeski's theory with a
general potential, which accommodates both chameleon and Vainshtein screening
mechanisms and provides a non-linear extension of the effective theory of dark
energy up to third order. Focus is on a recent non-linear model of the redshift
space power spectrum which has been shown to model the anisotropy very well at
relevant scales for the SPT framework, as well as capturing relevant non-linear
effects typical of modified gravity theories. We provide consistency checks of
the code against established results and elucidate it's application within the
light of upcoming high precision RSD data.
