COLLIDER PHYSICS FOR THE LATE 1980'S

Introduction
In these lectures, I shall discuss some topics in the standard model of strong
and electroweak interactions and how these topics are relevant for the high energy
colliders which will become operational in the next few years. Table 1 shows the
characteristics of the colliders that I shall discuss. Of the three +e- collider, LEP
and the SLC will spend most of their operation in studying the physics of the Z and
in making detailed tests of the Weinberg-Salam model. After its upgrade to LEPM
in the early 1990's, LEP will be able to study the physics of etc collisions above
the W pair threshold. Tristan will study QCD physics including the formation of
resonances in the collisions of two photons and, hopefully, toponium if the top quark
is within its energy range. The Tevatron collider will continue the type of physics
done at the SppS collider, and with its increased energy will be able to extend the
mass range over which we can search for new particles.
I shall begin with a discussion of radiative corrections in the Glashow-Weinberg-
Salam model,' stressing how these corrections may be measured at LEP and the
SLC. A brief discussion of CP violation will follow. This will be followed by a
discussion of the Higgs boson and the searches which can be carried out for it. I
shall then discuss some features of QCD which are relevant to hadron collides. This
discussion will complement the lectures of Luigi DiLella,2 who has shown impressive
evidence from the CERN SppS collider for the correctness of QCD. Finally I shall
discuss some of the problems which the standard model does not solve. I shall
indicate the energy ranges which are accessible at these new collider for the quest
for new physics. More details of the searches for new physics can be found in the
lectures of E. Eichten at last year's school.?
