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 $\text{Spin}(32)/{\mathbb{Z}}_{2}$ or $({E}_{8}\ifmmode\times\else\texttimes\fi{}{E}_{8})\ensuremath{\rtimes}{\mathbb{Z}}_{2}$ heterotic superstring theories for $p=7$, 6, 4, 0.
