Dasgupta, T. & Stefanski, B. (2000). Non-BPS States and Heterotic - Type I' Duality. Nuclear Physics B, 572(1-2), pp. 95-111. doi: 10.1016/s0550-3213(00)00039-0
Abstract
There are two families of non-BPS bi-spinors in the perturbative spectrum of the nine dimensional heterotic string charged under the gauge group $SO(16)\times SO(16)$. The relation between these perturbative non-BPS states and certain non-perturbative non-BPS D-brane states of the dual type I$^\prime$ theory is exhibited. The relevant branes include a $\Zop_2$ charged non-BPS D-string, and a bound state of such a D-string with a fundamental string. The domains of stability of these states as well as their decay products in both theories are determined and shown to agree with the duality map.
