Description

I describe how to construct new scalar field theories in four dimensions with attractive properties such as nonrenormalization theorems and interesting nonlinear classical dynamics. These generalized galileons are related to extra dimensional gravity models, and have a tight relationship to massive gravity models. Their properties suggest applications in inflation, late-time cosmic acceleration, and perhaps in tackling the hierarchy problem.
