A handout with this information is distributed at the first lecture and is also available in pdf format .
Lectures meet Mondays, Wednesdays and Thursdays from 16:30 to 17:20. They are officially in DSB B107, though I have been holding them in ABB-272 and will continue to do so (unless the attendance begins to make that room too small). Attendance to the lectures is certainly not compulsory, but if you come I do ask you to pay attention and not disrupt the class with personal conversation or social media. (My preference is to have our class be a laptop/smartphone-free zone.) I will do what I can to ensure that you do not have to gnaw your own arm off to stay awake.
The course textbook is Subatomic Physics, by Henley and Garcia, and has been ordered at the bookstore. I use this only occasionally for assignments and as an alternative point of view to my lecture notes (which my lectures will follow much more closely), so it is not obligatory to buy.
A possible alternative reference often used for courses like this is Introduction to Elementary Particles by Griffiths, though this has more of a particle physics (as opposed to nuclear) spin and although it describes Feynman rules it does so without quantum field theory and so does not really explain why they are what they are. I also sometimes draw material from my own book, The Standard Model: A Primer, which aims to use the Standard Model as a vehicle for introducing quantum field theory at a level appropriate to an introductory graduate class. For quantum field theory a book with a relatively light touch is Quantum Field Theory in a Nutshell by Tony Zee, and David Tong has a good set of lecture notes (again at a graduate level) at his Cambridge University webpage.
Because I spend half my time at Perimeter Institute I may be hard to find in my office, so it is worth setting up any appointments in advance. I am happy to meet however, so either catch me in class or tell me there that you intend to meet me in my office. (I usually do not just hang about the office unless I know students are coming by, so it is best to let me know in advance if you intend to stop in.) Otherwise, feel free to arrange another time with me on an individual basis. (I will make a point of being in my office for scheduled appointments, sometimes coming in from off campus, so if you do set up an appointment, please show up!)
The course TA is Gabriel Magill and meetings with him are probably best arranged by email at gmagill (at) perimeterinstitute.ca. His office hours are Thursdays from 1:00 – 1:45 in room ABB 327A.
The course work involves completing a (roughly) weekly assignment. Like any worthwhile subject, Subatomic Physic is a contact sport and so is only really learned by doing. It is very very strongly recommended to work the assignments even if you only audit the course.
By mutual agreement I will be issuing assignments during class on Wednesdays, and they are due in class the following Wednesday. If you do not hand them in then it is your own responsibility to get them to the TA (Gabriel), and it is his choice whether he marks work that is handed in late (or assesses a penalty for late work). Check out this term’s assignments here.
The term project is to summarize in your own words one of the classic papers of subatomic physics. Describe both what the paper’s intended point was, and why it was important (which are not always the same thing). You can work in groups if you wish, but if so when you submit your paper choice you should also submit a list of the others in your group.
Procedural details and a lengthy list of papers from which to choose are given here. Here are the deadlines (though do not wait for the deadlines before starting!):
Step one: choose a paper from the list (or you can choose one not on the list if you first get my approval for the paper you have in mind) and tell Gabriel which it is (and who your fellow group members are, if any) by Thursday March 15.
Step two: hand in your finished essay in class Thursday March 29.
A midterm test will be held in class on Thursday, March 1st 2018. The midterm provides the best possible practice for the final exam, so it would be silly not to write it. Those who do not write the midterm for whatever reason can avail themselves of Option B below. Be there or be square.
The Final Exam will be held during the April examination session.
The course marks are completely based on the weekly assignments, the midterm test, the term project and the final exam. The term mark will be computed from these according to whichever of the following formulae maximizes your final mark:
- A) Assignment: 20% Midterm: 20% Term Project: 20% Final Exam: 40%
- B) Assignment: 20% Midterm: 0% Term Project: 20% Final Exam: 60%
- C) Assignment: 20% Midterm: 20% Term Project: 10% Final Exam: 50%
- D) Assignment: 20% Midterm: 0% Term Project: 10% Final Exam: 70%
Part of the reason for providing you this menu of alternatives is to allow you to accommodate the imponderables of your own life, such as unexpected illnesses and the like. The purpose of doing so is to make this flexibility open to everybody in the class, and not just to those who wish to make special arrangements with me, or with the Associate Dean. So this my preferred way to deal with MSAF applications in this class.
Additional Work and Supplemental Exam:
Additional work will NOT be available for students who might wish to improve their marks. The standard McMaster rules apply regarding the availability of supplemental exams.
