Symmetries for Galileons and DBI scalars on curved space
Garrett Goon, Kurt Hinterbichler, Mark Trodden
We introduce a general class of four-dimensional effective field theories which include curved space Galileons and DBI theories possessing nonlinear shift-like symmetries. These ef…
General Embedded Brane Effective Field Theories
Garrett Goon, Kurt Hinterbichler, Mark Trodden
We present a new general class of four-dimensional effective field theories with interesting global symmetry groups. These theories arise from purely gravitational actions for (3+1…
Screening bulk curvature in the presence of large brane tension
Nishant Agarwal, Rachel Bean, Justin Khoury +1
We study a flat brane solution in an effective 5D action for cascading gravity and propose a mechanism to screen extrinsic curvature in the presence of a large tension on the brane…
Tackling Higher Derivative Ghosts with the Euclidean Path Integral
Michele Fontanini, Mark Trodden
An alternative to the effective field theory approach to treat ghosts in higher derivative theories is to attempt to integrate them out via the Euclidean path integral formalism. I…
