Physics with CDF

The success of S anti ppS detectors in isolating interesting parton-parton collisions clearly from the less interesting beam-beam background has made the prospect of TeV-I physics even more exciting because of the higher energy and higher luminosity that TeV-I is designed to deliver. In this report, discussion are focussed on important physics with CDF which are possible only at the higher energy and higher luminosity. Among those are testing the gauge structure of the electro-weak interaction, probing the compositeness scale of quarks, and studying W-decay channels with increased statistics. Investigations made include transverse momentum distribution, invariant mass distribution, energy flow distribution, rapidity distribution, and Drell-Yan cross sections. Results are described and discussed. The standard model has been established to a surprising degree by S anti p pS. That the observed masses of W and Z come within less than 10 % of the prediction has created more misteries on symmetry breaking mechanism. It is absolutely the must of TeV-I to go beyond the standard model. Since the Higgs discovery seems almost hopeless at CDF, alternates must be looked for somewhere else, namely the gauge coupling structure, compositeness, and SUSY. (Nogami, K.)
