Query: Summary Talk: First Workshop on Forward Physics and Luminosity
  Determination at the LHC   An attempt is made to summarize the discussion at the Workshop, except for
the panel discussion on the ability of the LHC detectors to accommodate forward
reactions. The Workshop focused on two main topics. The first topic was forward
physics at the LHC. Predictions were made for forward reactions, including
elastic scattering and soft diffractive processes, intopic was forward physics
at the LHC. Predictions were made for forward reactions, including elastic
scattering and soft diffractive processes, in terms of (multi) Pomeron
exchange, using knowledge gained at lower energies. The survival probability of
rapidity gaps accompanying hard subprocesses was studied. The nature of the
Pomeron, before and after QCD, was exposed, and some aspects of small x physics
at the LHC were considered. The second topic of the Workshop concerned the
accuracy of the luminosity measuring processes at the LHC. Attention
concentrated on three methods. The classic approach based on the optical
theorem, secondly, the observation of the pure QED process of lepton-pair
(l^+l^-) production by photon-photon fusion and, finally, the measurement of
inclusive W and Z production.
