Grading:

Approx 60% HW, 15% midterm, 25% final exam.

There will be approx 1 problem set assigned per week, due at the beginning of class after 1 week.
Late homework will be accepted at any time before the final exam for 50% credit.
Higher credit for late homework will be considered in the case of really creative excuses.

PDG ordering site

from which you should order your personal copies of the...

1. Particle Data Book
A pocket-sized 300-page booklet containing the Summary Tables and abbreviated versions of some of the other sections of the full Review of Particle Physics (see below).

2. Review of Particle Physics
A biennial review summarizing much of Particle Physics. 2000 new measurements from 700 papers plus data from previous editions are compiled and evaluated in Particle Listings and Summary Tables. Included are properties of gauge bosons, leptons, quarks, mesons, and baryons, plus searches for hypothetical particles such as Higgs bosons, heavy neutrinos, monopoles, and supersymmetric particles. There are many reviews, tables, and plots on topics such as Standard Model, particle detectors, probability, and statistics.

3. Pocket Diary for Physicists (optional but useful)
A pocket-sized calendar, suitable for recording personal engagements and addresses, that lists major international holidays, major high-energy physics conferences, and addresses and phone numbers of high-energy physics institutions.

4. Impress your friends: pronounce Linux correctly. (au file)
