摘要: We use the effective field theory for gravitational bound states, proposed by Goldberger and Rothstein, to compute interaction Lagrangian of a binary system at second post-Newtonian order. Throughout calculation, we metric parametrization based on temporal Kaluza-Klein decomposition test claim Kol Smolkin that this provides important calculational advantages. demonstrate how method efficiently in precision calculations, reproduce known results order equations motion harmonic gauge straightforward manner.
