A GEOMETRIC REALIZATION OF CONFINEMENT

We study the geometric realization of the Higgs phenomenon in type II string compactifications on Calabi-Yau manifolds. The string descripti on is most directly phrased in terms of confinement of magnetic flux, with magnetic charged states arising from D-branes wrapped around chai ns as opposed to cycles. The rest of the closed cycle of the D-brane w orld-volume is manifested as a confining flux tube emanating from the magnetic charges, in the uncompactified space. We also study correctio ns to hypermultiplet moduli for type II compactifications, in particul ar for type IIA near the conifold point.
