Nonsupersymmetric Heterotic Branes

Abstract

The common statement that any consistent quantum gravity theory contains dynamical objects with all possible charges suggests that there are still a number of hitherto-unidentified branes in string theory. Here we give the exact worldsheet description of near-horizon limits of nonsupersymmetric p-branes in ten-dimensional Spin(32)/Z_{2} or (E_{8}×E_{8})⋊Z_{2} heterotic superstring theories for p=7, 6, 4, 0.
