Homework
Homework due Feb 6: 1.19, 2.1, 2.2, 2.5, 2.6, 2.7, 2.8
Homework due Feb 13: 3.3, 3.4, 3.6, 3.15, 3.16, 3.17, 3.25 + At the HERA collider, 27.5 GeV electrons collided head-on with 920 GeV protons. What was the center of mass energy?
Homework due Feb 20: 4.8, 4.10, 4.13, 4.29, 4.30, 4.38 + Tell me in which isospin states can these combinations exist? a) pi^+ pi^- pi^0, b) pi^0 pi^0 pi^0, c) p n pi^-, d) p pi^0 pi^-. Also, send me before class a proposed paper topic for your final presentation
Homework due March 1: 6.8, 6.12, 6.14, 6.15. Also, if a 1 GeV muon neutrino is fired at a 1 m-thick block of iron-56 with density 7.87x10^3 kg/m^3 and the average neutrino-nucleon σ=8x10^{-39} cm^2, what is the probability that the neutrino interacts in the block?
Homework due March 20: Send me before class an outline of your final presentation
Homework due March 27: 7.6,7.13,7.18,7.48,7.49 (use your answer to 6.8 for part e). Also, before class that day, send me at least two references that you are going to use for material and/or background information and/or reading to prepare for your talk, NOT including the main paper you are presenting. Also tell me in the email (briefly) what you are using them for. A good starting point is some references or links from that paper, of course.
Homework due April 5: 8.17,8.24. Also, given a highly boosted W boson decaying to quarks, show that the cone size of a jet containing the two quarks from its decay is roughly given by dR ~ 2*mW/pT. Given jet cone sizes of dR ~1, this implies a pT of ~160 GeV.
Homework due April 26: 9.5,9.16, 9.29, 9.30, 9.31
