New results at 3PN via an effective field theory of gravity

Abstract

NRGR, an Effective Field Theory approach to gravity, has emerged as a powerful tool to systematically compute higher order corrections in the Post-Newtonian expansion. Here we discuss in somehow more detail the recently reported new results for the spin-spin gravitational potential at third Post-Newtonian order.Comment: 4 pages, talk at the 11th Marcel Grossmann meeting, Berlin, july 200
