Abstract

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× Smin 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 geometries correspond to field theories with UV conformal fixed points, and they undergo decompactification in the IR region. In the case of AdS3, we compute the central charge of the corresponding conformal field theory. © 2008.
