Membrane Scattering in Curved Space with M-Momentum Transfer
We study membrane scattering in a curved space with non-zero M-momentum p11 transfer. In the low-energy short-distance region, the membrane dynamics is described by a three-dimensional N = 4 supersymmetric gauge theory. We study an n-instanton process of the gauge theory, corresponding to the exchange of n units of p11, and compare the result with the scattering amplitude computed in the low-en...
متن کاملField Theory in Curved Space and the Definition of Momentum
Some general remarks are made about the quantum theory of scalar fields and the definition of momentum in curved space. Special emphasis is given to field theory in anti-de Sitter space, as it represents a maximally symmetric space-time of constant curvature which could arise in the local description of matter interactions in the small regions of space-time. Transform space rules for evaluating...

متن کاملD-Branes in Curved Space
We review recent work on the structure of the action forN D0-branes in a curved background, with emphasis on the meaning of space-time diffeomorphism invariance. Talk given at the Francqui Colloquium, 2001, “Strings and Gravity: Tying the Forces Together.” E-mail: [email protected] Since their introduction in 1995 [1], D-branes have played a tremendously important role in string theory. It...
متن کاملD-Branes in Curved Space
We obtain actions for N D-branes occupying points in a manifold with arbitrary Kähler metric. In one complex dimension, the action is uniquely determined (up to second order in commutators) by the requirement that it reproduce the masses of stretched strings and by imposing supersymmetry. These conditions are very restrictive in higher dimensions as well. The results provide a noncommutative ex...
