Students are expected to know quantum mechanics at the PHYS 711, 712 graduate level and particle physics at the level of PHYS 723 before they take this course. Only students who have done well in PHYS 711/712 and in PHYS 723 should take this course. They should also have taken undergraduate courses in modern physics and nuclear / particle physics.
Attendance: Mandatory.
Homework = 70%,
Project presentation = 15%,
Project Report = 15%.
You will need at least 90% for an A, 85% for a B+, 75% for a B,
70% for a C+ and 60% for a C.
Homework:
Homework problem sets will be assigned once every 1 or 2 weeks and will
be due one week from when they are distributed.

The course begins by using gamma matrix technology to compute simple electromagnetic scattering problems. We continue with the weak and strong interactions, focusing first on low-energy weak interactions and later on higher energy processes. We will then continue with a description of gauge invariance and the standard model. Contemporary experimental studies will include neutrino physics, the study of CP violation using heavy flavors and the search for the Higgs boson. Finally, we will explore physics beyond the standard model and discuss experiments designed to study possible extensions of the standard model. In particular we will attempt to gain some familiarity with various Higgs scenarios and supersymmetry and to understand the motivations and design of experiments at the LHC and the LC.
While much of the material is contained in the text by Halzen and Martin and last semester's text by Griffiths, from time to time we shall be forced to consult other texts and research publications (particularly in the second half of the course).
It is important to pick a topic relevant to the course, such as searches for new particles etc. Off-course topics will be discouraged, but may be allowed on a case-by-case basis. It is important to keep it simple; to have a brief (5-minute) introduction with the background theory and results simply stated (not derived); to focus on a single measurement if possible; to work out some numbers, e.g., number of signal events, background events, need for specific apparatus, etc. It is also useful to your fellow students to show how the results derive from the observations, how they cannot be produced by the backgrounds, and what is the significance of the result. Generally speaking, trying to cover too much ground is not a good idea. If you have a good command of the subject and wish to display it, pelase do so in the report. Under no circumstances should anything in the report be a copy of anything published or found on the web. You may cut and paste figures, but all the words must be your own. Provide references for all your sources, and for further reading. Make it interesting! If you understand your subject matter well, your presentation will go very well.
Examples of good topics are provided by some of the recent physics Nobel laureates and their work, see list below. Note that some names are dropped because their work was covered in the last semester (e.g., Murray Gell-Mann), some for other reasons. Recommended are:
