Dipoles in Impact Parameter Space and Rapidity

We describe the DIPSY model for initial state evolution and the implementation of this in an event generator for producing fully exclusive hadronic final states. The model is formulated in impact parameter space and rapidity. Including non-leading and nonlinear effects, it gives a unique picture of fluctuations and correlations in the initial state parton evolutions. It also gives an impact-parameter- dependent description of the final state, allowing for new insights into the hadronization process in dense collision environments.
