Ridge correlations and high energy QCD evolution
Dr. Kevin Dusling (North Carolina State University)

Abstract: I will begin this talk with an overview of the two particle correlation measurements at RHIC and the LHC.  Emphasis will be on the recently measured near--side angular correlation between particles having a large separation in rapidity known as ``The Ridge". Causality dictates that these correlations must have developed at proper times well before a fm/c and therefore, must be intrinsically related to multi-parton correlations in the nuclear wavefunctions themselves.  I will show how a description of the hadron/nuclear wave function in the Color Glass Condensate  framework of high energy QCD provides a natural explanation for the ridge seen in both proton--proton and nucleus--nucleus collisions.
