Galilean currents and charges (1011.3057v1)
Published 12 Nov 2010 in hep-th, astro-ph.CO, gr-qc, and physics.class-ph
Abstract: We derive the Noether currents and charges associated with an internal galilean invariance---a symmetry recently postulated in the context of so-called galileon theories. Along the way we clarify the physical interpretation of the Noether charges associated with ordinary Galileo- and Lorentz-boosts.
