[1104.4608] Nordstrom's scalar theory of gravity and the equivalence principle

Authors: Nathalie Deruelle

Date: 24 Apr 2011

Abstract: Nordstrom's theory of gravity, which describes gravity by a scalar field in flat spacetime, is observationally ruled out. It is however the only theory of gravity with General Relativity to obey the strong equivalence principle. I show in this paper that this remarkable property is true beyond post-newtonian level and can be related to the existence of a 'Nordstrom-Katz' superpotential.
