Query: Prospects for Diffractive Physics with the CDF Forward Detectors at the
  Tevatron   The Forward Detector upgrade project at CDF is designed to enhance the
capabilities for studies of diffractive physics at the Tevatron during Run II.
Studies of hard diffraction and very forward physics are some of the topics
that can be addressed in the next few years at the Tevatron. The program for
diffractive physics, including the detectors and their commissioning, is
discussed here. All the detectors have been installed and are presently
collecting data.
