High Energy Physics - Standard Model

**Instructor:** Hsin-Chia Cheng (cheng [at]
physics.ucdavis.edu)

**Time & Place:** Tue & Thu 2:40-4:00 PM, 185 PHYSICS

**Office Hours:** Tue 1:30-2:30PM, Thu, 4-5PM

**Prerequisites:** PHY230AB

**Website:** http://cheng.physics.ucdavis.edu/teaching/245B-w19

**Homework:** Homework assignments and solutions, as well as
lecture notes can be found on the Canvas course page

Reader: Cameron Langer (cklanger [at]
ucdavis.edu), 394 Physics

**Textbook:** We will not follow any particular book exactly.
A recommended book which is close to our approach is "The Standard
Model and Beyond" by Paul Langacker. The later chapters of
"An Introduction to Quantum Field Theory" by Peskin and Schroeder
is useful for the first half of the course. Some other useful
books are

- Dynamics of the Standard Model, Donoghue, Golowich and
Holstein

- Weak Interactions and Modern Particle Theory, Howard Georgi

- Gauge Theory of elementary particle physics, Cheng and Li

**Grading:** There will be homework assignments every week.
Doing the problem sets is an extremely important part of learning.
You can't learn the subject by just listening to the lectures
without working through things by yourself. You can discuss the
problem sets with your classmates, but you are not allowed to copy
other people's homework. Each of you is required to write up your
own homework following your own understandings. Each problem set
is due about one week after its assignment in class. No late homework will be accepted
so even if you couldn't finish you should turn in what you have
done. The solutions will be available on the Canvas course
website. The homework will count 70% of the final grade. A
final problem set (take-home final) will count 30% of the final
grade.
