摘要：
In this proceedings contribution we summarize a series of results on nonlinear perturbation theory for modified gravity models, in which a scalar field changes the gravitational dynamics at cosmic scales. We discuss its effects on large scale structure, focusing on screenings and the power spectrum of matter fields and tracers. We also discuss a redshift space distortions model for modified gravity and the departures from the LCDM model.
