The Revival of (0,2) Linear Sigma Models
arXiv:1010.4667 · doi:10.1142/S0217751X11051366
Abstract
Compactifications of the heterotic string are a viable route to phenomenologically realistic vacua and interesting new mathematics. While supergravity aspects of heterotic compactifications are largely well-understood their worldsheet description remains largely unexplored. We review recent work in developing linear sigma model techniques aimed at elucidating the underlying worldsheet description.
