چکیده
In this paper we shall show how to construct two new superstring theories in dimensions 12 and 16 which satisfy the Lorenz symmetries in 4 dimensions after compactification but which satisfy different symmetry groups before compactification. The arguments are also applied to supergravity theory. We write the first few terms of these new supergravity actions. The new supergravity actions can be expressed in terms of 3-branes and 5-branes respectively. PACS numbers: 04.65+e,04.70.s Submitted to: Class. Quantum Grav.

Nondecoupling of maximal supergravity from the superstring.
We consider the conditions necessary for obtaining perturbative maximal supergravity in d dimensions as a decoupling limit of type II superstring theory compactified on a (10-d) torus. For dimensions d=2 and d=3, it is possible to define a limit in which the only finite-mass states are the 256 massless states of maximal supergravity. However, in dimensions d>or=4, there are infinite towers of a...
متن کاملDecoupling Supergravity from the Superstring
We consider the conditions necessary for obtaining perturbative maximal supergravity in d dimensions as a decoupling limit of type II superstring theory compactified on a (10 − d)-torus. For dimensions d = 2 and d = 3 it is possible to define a limit in which the only finite-mass states are the 256 massless states of maximal supergravity. However, in dimensions d ≥ 4 there are infinite towers o...
متن کاملSupergravity in 10 + 2 Dimensions as Consistent Background for Superstring
We present a consistent theory of N = 1 supergravity in twelve-dimensions with the signature (10, 2). Even though the formulation uses two null vectors violating the manifest Lorentz covariance, all the super-space Bianchi identities are satisfied. After a simple dimensional reduction to ten-dimensions, this theory reproduces the N = 1 supergravity in ten-dimensions, supporting the consistency ...
متن کاملSupergravity Theories in D ≥ 12 Coupled to Super p - Branes
We construct supergravity theories in twelve and thirteen dimensions with the respective signatures (10, 2) and (11, 2) with some technical details. Starting with N = 1 supergravity in 10+2 dimensions coupled to Green-Schwarz superstring, we give N = 2 chiral supergravity in 10+2 dimensions with its couplings to super (2 + 2)-brane. We also build an N = 1 supergravity in 11+2 dimensions, couple...
متن کاملCompactification of D=11 Supergravity on Spaces of Exceptional Holonomy
We investigate the compactification of D=11 supergravity to D=5,4,3, on compact manifolds of holonomy SU(3) (Calabi-Yau), G 2 , and Spin(7), respectively , making use of examples of the latter two cases found recently by Joyce. In each case the lower dimensional theory is a Maxwell/Einstein supergravity theory. We find evidence for an equivalence, in certain cases, with heterotic string com-pac...
