On the supersymmetrization of Galileon theories in four dimensions

We use on-shell amplitude techniques to study the possible N=1 supersymmetrizations of Galileon theories in 3+1 dimensions, both in the limit of decoupling from DBI and without. Our results are that (1) the quartic Galileon has a supersymmetrization compatible with Galileon shift symmetry (ϕ→ϕ+c+bμx...
