The Sirens of Eleven Dimensions
While most theorists are tied to the mast of four dimensions, some have found it irresistible to speculate about eleven dimensions, the domain of M-theory. We outline a program which starts from the light-cone description of supergravity, and tracks its divergences to suggest the existence of an infinite component theory which in the light-cone relies on the coset F4/SO(9), long known to be lin...
متن کاملOne Loop in Eleven Dimensions
Four-graviton scattering in eleven-dimensional supergravity is considered at one loop compactified on one, two and three-dimensional tori. The dependence on the toroidal geometry determines the known perturbative and non-perturbative terms in the corresponding processes in type II superstring theories in ten, nine and eight dimensions. The ultraviolet divergence must be regularized so that it h...
متن کاملTwo loops in eleven dimensions
The two-loop Feynman diagram contribution to the four-graviton amplitude of eleven-dimensional supergravity compactified on a two-torus, T , is analyzed in detail. The Schwinger parameter integrations are re-expressed as integration over the moduli space of a second torus, T̂ , which enables the leading low-momentum contribution to be evaluated in terms of maps of T̂ 2 into T . The ultraviolet di...
متن کاملOpen Supermembranes in Eleven Dimensions
We consider open supermembranes in an eleven dimensional background. We show that, in a flat space-time, the world-volume action is kappa-symmetric and has global space-time supersymmetry if space-time has even dimensional topo-logical defects where the membrane can end. An example of such topological defects is provided by the space-time with boundaries considered by Horava and Witten. In that...
متن کاملSupersymmetry in Dimensions Beyond Eleven
Spacetime superalgebras with 64 or less number of real supercharges, containing the type IIB Poincaré superalgebra in (9, 1) dimensions and the N = 1 Poincaré superalgebra in (10, 1) are considered. The restriction D ≤ 14, and two distinct possibilities arise: The N = (1, 0) superalgebra in (11, 3) dimensions, and the N = (2, 0) superalgebra in (10, 2) dimensions. Emphasizing the former, we des...
