Looking Forward in QCD

Over the last decade QCD has produced a quantitative description of many high energy processes. However the successes are mostly restricted to the description of inclusive hard processes. We are still lacking an understanding of soft strong interactions, including the origin of the total cross sections and diffraction as well as hard physics at small-x. Moreover the soft and small-x dynamics and hard dynamics intertwine delicately at the Tevatron energies and beyond, both in new particle production and in hard exclusive or semi-exclusive processes. Future experiments can dramatically contribute to the understanding of this physics if they extend the acceptance to the forward direction. The topics to be discussed include a 3-dimensional picture of a fast nucleon at different virtualities, challenges and paradoxes of small-x physics and ways to address them in inclusive and diffractive forward hard phenomena, and the presence of correlations in the transverse distribution of partons in the nucleon as revealed by the CDF photon + three jet production study.
