N-Body Simulations of DGP and Degravitation Theories

Khoury, Justin, Wyman, Mark

Understand

We perform N-body simulations of theories with infinite-volume extra dimensions, such as the Dvali-Gabadadze-Porrati (DGP) model and its higher-dimensional generalizations, where 4D gravity is mediated by massive gravitons.

The longitudinal mode of these gravitons mediates an extra scalar force, which we model as a density-dependent modification to the Poisson equation.
This enhances gravitational clustering, particularly on scales that have undergone mild nonlinear processing.
While the standard non-linear fitting algorithm of Smith et al.
