Equations of motion and Galilei invariance in D-particle dynamics Original Research Article

As a continuation of our previous work on the multi-body forces of D-particles in supergravity and Matrix theory, we investigate the problem of motion. We show that the scattering of D-particles including recoil derived in Matrix theory is precisely reproduced by supergravity with the discrete light-cone prescription up to the second order in 11-dimensional Newton constant. An intimate connection of recoil and Galilei invariance in supergravity is pointed out and elucidated.
