Long Range Rapidity Correlations in the Glasma and the Near Side Ridge in Heavy Ion Collisions

We outline a formalism to compute multi-gluon production with arbitrary rapidity separations in nucleus-nucleus collisions at high energies. We discuss how this provides a "chronometer" of the early time strong color field dynamics in heavy ion collisions as well as a probe of multi-gluon correlations in the nuclear wavefunction. We show how our formalism provides a simple geometrical interpretation of striking results from the RHIC experiments on near side “ridge-like” two particle correlations.
