Comments on D-Brane and SO ( 2 N ) Enhanced Symmetry in Type II String

Abstract

We propose a configuration of D-branes welded by analogous orbifold operation to be responsible for the enhancement of SO(2N) gauge symmetry in type II string compactified on theDn-type singular limit of K3. Evidences are discussed from theDn-type ALE and D-manifold point of view. A subtlety regarding the ability of seeing the enhanced SO(2N) gauge symmetry… (More)
