We study W/Z/DY + jet events where the W/Z/DY boson is produced in the forward direction of one of the colliding protons and a jet is produced in the forward direction of the second proton. The resulting large rapidity difference between the final states then opens up the phase space for BFKL evolution which we would like to study in more detail. As a by-product of our study, we also provide an analytic expression for the high energy re-summed exclusive partonic W/Z + n jet cross-section in moment space. To construct the BFKL re-summed cross-section we determine an analytic expression for the exclusive W/Z/DY impact factor in (gamma, n) space which is combined with BFKL Green's function and jet impact factor. In particular, both impact factors are determined for non-zero conformal spin and allow therefore for the study of angular correlations. First numerical results for a number of observables which allow to isolate and test BFKL evolution are presented.
