Stringy tachyonic instabilities of non-supersymmetric Ricci flat backgrounds
Stringy tachyonic instabilities of non-supersymmetric Ricci flat backgrounds
A bstract Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy. We use worldsheet conformal field theory to investigate instabilities of Type II superstring theories on compact, Ricci flat, spin 3-manifolds including a worldsheet description of their …
