Covariant multi-galileons and their generalisation

Article

Abstract

We find a covariant completion of the flat-space multi-galileon theory, preserving second-order field equations. We then generalise this to arrive at an enlarged class of second order theories describing multiple scalars and a single tensor, and conjecture that these are a multi-scalar version of Horndeski’s most general scalar-tensor theory.
