## PHY6648: Quantum Field Theory I

This course is the first semester of a three semester course on
modern quantum field theory and the standard model of elementary
particles. Although the course is mandatory for
students interested in high energy particle physics, it should
also be valuable to students of other specialties including
condensed matter physics and atomic and molecular physics.
For example, in the
first semester we shall develop, in our treatment of the
Dirac equation, the technique
of second quantization so useful in many body theory. Furthermore,
the emphasis of the whole course is on Quantum Electrodynamics, which
is essential to an understanding of all areas of physics.
Quantum Field Theory I is the natural continuation of the
graduate quantum mechanics courses PHY6645-46.
## PHZ6358: Standard Model of Elementary Particles I/
Quantum Field Theory II

This course is the second semester of
quantum field theory and the standard model. The first part of the course
will deal with 1 loop Quantum Electrodynamics (QED) and its renormalization.
Then nonabelian gauge theory will be introduced with applications
in QCD the gauge theory of strong interactions. The gauge group
of the standard model will be presented.
Spontaneous breaking
of global symmetries will be introduced with first applications to
chiral symmetry breaking and pions as Goldstone bosons. Then
spontaneous breaking of local (i.e. Gauge) symmetries will
be discussed with application to the electroweak sector of the
standard model.
## PHZ7359: Standard Model of Elementary Particles II and
Quantum Field Theory II

Continuation of PHZ6358.

### Announcements, Spring2018

We will probably have to reschedule our class time to allow all interested
students to take the course. Please try to make the first class meeting
at 3 pm on Monday 8 Jamuary 2018 to discuss this! If you can't make this time,
please see me before that class time on Monday or send me
an email with a list of the times you CAN NOT meet for class.
Our class time and room have been changed to MWF 9th period (4:05-4:55pm)
in NPB1200. Our second class on Wednesday wull be at this new time and
place.
Friday office hour changed from 7th to 5th period.

Please be aware that my lecture notes are being typed in
real time, so there will be frequent updates. I will post them as
soon as they are available!
Solution Set 3 posted 26 February 2018 and lecture notes updated.

Please consider the possibility of using Set 7 as the final exam for this
course. Let me know whether or not you like this idea.
Take home final exam posted 6 April 2018 and Lecture notes updated. I
remind you that no collaboration is allowed on the exam problems.

**Faculty Course evaluations** will be conducted entirely
on line. They open 14 April 2018
and will continue until 27 April 2017..
These evaluations provide very important feedback,
so it is essential that we all do our best to maximize the number of responses.
You can access the evaluation form at your leisure from the web site:
https://evaluations.ufl.edu/evals/
where you can find instructions and links to a gatorlink login page.
It is probably a good idea if you bookmark the page so you can easily find
it in the future.

### Homework Assignments

In the homework assignments, I will refer to problems in
Srednicki's book by prefixing the problem number with S.
Note that there are many problems in his book which ask the reader
to fill in gaps in the preceding discussion (e.g. S 2.1 through 2.7).
I will generally not assign such problems to be graded, but
you should nonetheless make sure you understand how to do them.

### Information on Final Exam

The take home final examination is posted above and is due in my office
by 5 pm 30 April..
In grading the final, points will be deducted for errors in
calculation and logic. This is in sharp contrast to the
grading of the homework which was based more on the
amount of work done than its accuracy.
Absolutely no collaboration is allowed. Each student's exam
must be entirely his own work.

We shall not cease from exploration

And the end of all our exploring

Will be to arrive where we started

And know the place for the first time.

- T. S. Eliot
