Ph 135c Introduction to Particle Physics Spring 2017 |

**Course logistics**

- Lectures held
**Tuesdays at 1:00pm**and**Thursdays at 1:00pm**in 248 Lauritsen. - Homeworks due Tuesday before 1:00pm. Please turn them in to Sung's mailbox in Bridge Annex.
- TA: Sungbong Chun <winnety9 at caltech dot edu>. Office hours: Monday at 4pm in Lauritsen 457.

**Course materials**

- "Introduction to Elementary Particles", David Griffiths (Second, Revised Edition).
*The older first edition is okay in a pinch. It is sorely out of date in places and uses a different format for Feynman diagrams, but these aren't absolute show stoppers. If you can get the second edition, I highly recommend doing so.* - "Review of Particle Physics", Particle Data Group. The material is all online at http://pdg.lbl.gov, but you can order a free hard copy from the site if you like paper.
- A variety of other materials will be provided, particularly for the second half of the term.

**Course description**

This course is designed to give you a working understanding of the field of particle physics. This is a broad topic, including theory and experiment, historical developments and current activities, accelerators and detectors, terrestrial and astrophysical systems, and more. Ten weeks is a criminally short amount of time to cover the field, but we will still dive deep into the material where possible.

The course is split roughly into two parts. The first half of the course covers the Standard Model from a theoretical and calculational perspective. This half will feel like a traditional course as we work through key chapters in the excellent Griffiths textbook. In the second half of the course, we will look at experimental methods and particular physical systems. These topics will be treated through a mix of lecture material, supplemental readings, homework problems, and (where suitable) student contributions.

There will be no final exam, but there will be a final project. The format of this project will be discussed in class.
