Abstract
Virtual photon scattering in e+e- collisions can result in events with the electron-positron pair produced at large rapidity separation in association with hadrons. The BFKL equation resums large logarithms that dominate the cross section for this process. After a brief overview of analytic BFKL resummation and its experimental status, we report on a Monte Carlo method for solving the BFKL equation that allows kinematic constraints to be taken into account. We discuss results for e+e- collisions using both fixed-order QCD and the BFKL approach. We conclude with some brief comments on the status of NLL calculations.
