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.

These evaluations provide very important feedback,
so it is essential that we all do our best to maximize the number of responses.

Information on Final Exam
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 will be allowed. Each student's exam
must be entirely his own work.
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.

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.

And the end of all our exploring
Will be to arrive where we started
