Three Graviton Scattering in M-Theory
The leading eikonal S-matrix for three graviton scattering in d = 11 supergravity and Matrix Theory are shown to precisely agree. The result unifies the source-probe plus recoil approach of Okawa and Yoneya and relaxes the restriction imposed by those authors that all D-particle impact parameters and velocities are mutually perpendicular. Furthermore, the unified S-matrix approach facilitates a...
متن کاملOn Graviton Scattering Amplitudes in M-Theory
We compute graviton scattering amplitudes in M-theory using Feynman rules for a scalar particle coupled to gravity in eleven dimensions. The processes that we consider describe the single graviton exchange and the double graviton exchange, that in M(atrix) theory correspond to the v/rand v/r-term respectively. We further show that the v/r-term appearing in M(atrix) theory at two-loops can be ob...
متن کاملGraviton scattering amplitudes in M theory
We compute graviton scattering amplitudes in M theory using Feynman rules for a scalar particle coupled to gravity in eleven dimensions. The processes that we consider describe the single graviton exchange and the double graviton exchange, that in M~atrix! theory correspond to the v/r and v/r term, respectively. We argue that the v/r term appearing in M~atrix! theory at two loops can be obtaine...
متن کاملGraviton scattering in matrix theory and supergravity
I briefly review recent work on the comparison between two and three graviton scattering in supergravity and matrix theory 1 Motivations In the low-energy regime, M-theory is D = 11, N = 1 supergravity. In the matrix model the fundamental degrees of freedom of M-theory are 0-branes (that is, Derichlet particles). For this model to be a correct description of M-theory, it must then reproduce sup...
متن کاملInfrared behavior of graviton-graviton scattering
The quantum effective theory of general relativity, independent of the eventual full theory at high energy, expresses graviton-graviton scattering at one loop order O ( E4 ) with only one parameter, Newton’s constant. Dunbar and Norridge have calculated the one loop amplitude using string based techniques. We complete the calculation by showing that the 1 d−4 divergence which remains in their r...
