# Bi-galileon theory II: phenomenology

@article{Padilla2010BigalileonTI, title={Bi-galileon theory II: phenomenology}, author={Antonio Padilla and Paul M. Saffin and Shuang-Yong Zhou}, journal={Journal of High Energy Physics}, year={2010}, volume={2011}, pages={1-30} }

We continue to introduce bi-galileon theory, the generalisation of the single galileon model introduced by Nicolis et al. The theory contains two coupled scalar fields and is described by a Lagrangian that is invariant under Galilean shifts in those fields. This paper is the second of two, and focuses on the phenomenology of the theory. We are particularly interesting in models that admit solutions that are asymptotically self accelerating or asymptotically self tuning. In contrast to the…

A theory of the quasidilaton is an extension of massive gravity by a scalar field, nonlinearly realizing a certain new global symmetry of the Lagrangian. It has been shown that unlike pure massive…
