Short Distance Contributions to Graviton-Graviton Scattering: Matrix Theory versus Supergravity
We study graviton scattering in the presence of higher dimensional operators – particularly, R4 – arising from loop effects. We find that the results do not correspond to any known terms in the effective action of Matrix Theory, thus lending support to the idea that the finite N Matrix Theory has no simple relation to supergravity with large compactification radii. 1 Work supported in part by a...
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 کاملSupergravity and matrix theory do not disagree on multi-graviton scattering
We compare the amplitudes for the long-distance scattering of three gravitons in eleven dimensional supergravity and matrix theory at finite N . We show that the leading supergravity term arises from loop contributions to the matrix theory effective action that are not required to vanish by supersymmetry. We evaluate in detail one type of diagram—the setting sun with only massive propagators—re...
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...
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...
