Past Exam Questions: PastPapers.pdf
(These look okay if you print them out.) There’s two questions that were not covered this year. The first part of the 4th short question, and the whole of the 5th short question.

Lecture Slides and Handouts
The Particle Physics module of physics 3 provides an introduction to the Standard Model of Particle Physics. We’ll discuss the particles that make up the model, the forces that carry the interactions between them, and see how such interactions are measured.
Corrections (pdf file of most of the corrections: Corrections2008.pdf)
(posted pdfs have these corrections implemented)
Lecture 1, slide 15: 4th line in the baryon part of the table. Should read neutron (udd) (NOT ddd)!
Lecture 2, slide 6: last line of equation. Should be 2 in front of last two terms:
New (and not in list handed out): Lecture 2, slide 7, equation should read:
Lecture 2, slide 10: Following equation should read (sign is wrong on last term):
Lecture 3, slide 2: In both the Schödinger equation and the Klein-Gordon equation the first ℏ on the LHS, should be squared.
Lecture 3, slide 5: Under the feynman diagram, M is just proportional to the expression:
Lecture 3, slide 12: In the first summary box, first bullet point should be:
“a negative energy particle travelling backwards in time”. (Not a positive energy one).
Lecture 5, slide 6: The bottom table should have the strange quark strangeness -1, not the down quark.
Up +2/3 |½, +½> 0
Down −1/3 |½, −½> 0
Strange −1/3 |0, 0> -1
Lecture 6, Slide 12: Under the Feynman diagrams it should read: “For one type of quark,
Some of the powers are wrong.
Lecture 8, Slide 15: Final equation should be:
Numerator on second fraction should be Vus2
Lecture 9, Slide 2: “We’ve seen already that wherever a γ boson can be exchanged a Z can also be exchanged” (need to swap γ and Z: subtle, but important, difference in meaning)
