1210.4026 (Antonio Padilla et al.)

Covariant multi-galileons and their generalisation    [PDF]

Antonio Padilla, Vishagan Sivanesan
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.
