  We discuss high energy hadronic collisions within the theory of the Color
Glass Condensate. We point out that the initial electric and magnetic fields
produced in such collisions are longitudinal. This leads to a novel string like
description of the collisions, and a large Chern-Simons charge density made
immediately after the collision. The presence of the longitudinal magnetic
field suggests that essential to the description of these collisions is the
decay of Chern-Simons charge.
