High Pt Dijet production in ep/eA DIS at small x (high energy) involves the expectation value of a trace of four Wilson lines, i.e. the quadrupole. At leading power the isotropic part can be expressed as the conventional Weizsacker-Williams gluon distribution. On the other hand, the distribution of linearly polarized gluons determines the amplitude of the ~ cos(2phi) anisotropy of the transverse momentum imbalance. I shall also discuss the operator that determines the next-to-leading power correction, its expectation value in a Gaussian theory (at large Nc), and the resulting .
