Abstract

I first explain how collider physics (at the LHC, and at possible future colliders) differ at the fundamental level from all the other physics in the precision and cosmic fronteers. If something is discovered or excluded at collider experiments, those observation becomes immediately the starting point of our pursuit of physics behind the SM.

 

Because of this peculiar property of collider physics, we should try to be as open minded as possible in our search for new physics at colliders. On the other hand, that all known physics are dictated by the SM gives very strong constraints on the possible form of new physics that can appear.

 

In the first lecture, I would like to review the SM of particle physics, and show how invariance under the unitary and Lorentz symmetries dictates the properties of the particles and their interactions.

 

In the second lecture, I may try to explain what we can study at proton proton collisions at high energies.

 

In the third lecture, I may use a particular collision channel, say, a collision of two up quarks, and show what kind of particles can be produced in the channel,and how to detect them.
