Some significant physics objectives of the p anti p collider

The p anti p collider will open a new range of centre-of-mass energies with at least five years of advance with respect to ISABELLE and presumably before the corresponding programme at Fermilab. It is clearly impossible within the available time to give a comprehensive review of the major experimental activities. I shall therefore discuss a few topics which, I believe, are particularly significant: (1) large psub(T)-effects for jets and single particles, (2) search for intermediate bosons, (3) search for Higgs particles, (4) weak interactions without bosons, (5) production of very narrow charmonium-like resonances. At the end I would like to describe briefly the general-purpose detector which is planned for one of the interaction regions around the SPS. (orig.)
