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

High Energy Physics - Theory 2009-10-30 v1

Abstract

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