Description
I will talk about non-BPS branes in heterotic superstring theories. These branes are characterized by topologically nontrivial gauge field configurations on the sphere surrounding the branes. I discuss exact worldsheet theories for the near horizon limit. The worldvolume theories on the branes may be non-Lagrangian, nonsupersymmetric systems in higher dimensions, and they have very nontrivial properties related to anomalies and chiral fermions.
