摘要：We present measurements of the spatial clustering statistics in redshift space of various scalar field modified gravity simulations. We utilise the two-point and three-point correlation functions to quantify the spatial distribution of dark matter halos within these simulations and thus discriminate between the models. We compare Λ cold dark matter (ΛCDM) simulations to various modified gravity scenarios and find consistency with previous work in terms of two-point statistics in real and redshift space. However, using higher-order statistics such as the three-point correlation function in redshift space we find significant deviations from ΛCDM hinting that higher-order statistics may prove to be a useful tool in the hunt for deviations from General Relativity.
