Some significant physics objectives of the $p\overline{p}$ collider

The p-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. The author therefore discusses a few topics which are particularly significant: large p/sub T/-effects for jets and single particles; search for intermediate bosons; search for Higgs particles; possible weak interactions without bosons and production of very narrow charmonium-like resonances. At the end the author describes briefly the general-purpose detector which is planned for one of the interaction regions around the SPS (LSS5). (7 refs).
