Generation of spatiotemporal correlated noise in 1+1 dimensions.

We propose a generalization of the Ornstein-Uhlenbeck process in 1+1 dimensions which is the product of a temporal Ornstein-Uhlenbeck process with a spatial one and has exponentially decaying autocorrelation. The generalized Langevin equation of the process, the corresponding Fokker-Planck equation, and a discrete integral algorithm for numerical simulation are given. The process is an alternat...

We report a search for large extra spatial dimensions in p¯ p collisions at a center of mass energy of 1.8 TeV at the Tevatron. We present recent DØ results on graviton-mediated exchange processes, using events containing a pair of electrons or photons. No evidence for signal is found, allowing to place the most restrictive lower limits on the effective Planck scale at the order of 1 TeV for se...

We obtain a large class of smooth Lorentzian p-brane wormholes in supergravities in various dimensions. They connect two asymptotically flat spacetimes. In cases where there is no dilaton involved in the solution, the wormhole can connect an AdSn × Sm in one asymptotic region to a flat spacetime in the other. We obtain explicit examples for (n,m) = (4, 7), (7, 4), (5, 5), (3, 3), (3, 2). These ...

The N=2 superconformal (or super-Virasoro) algebras in two dimensions are three complex Lie superalgebras: the Neveu-Schwarz superalgebra [1], the Ramond superal-gebra [1], the twisted superalgebra [2], which are denoted as A, P, T , resp., or G when a statement holds for all three superalgebras. They have the following nontrivial super-Lie brackets :
