Homework
Griffiths 1.19, 2.1, 2.2, 2.5, 2.6, 2.7, 2.8 due Feb 5
Griffiths 3.3, 3.4, 3.6, 3.15, 3.16, 3.17, 3.25. Also: At the HERA collider, 27.5 GeV electrons collided head-on with 920 GeV protons. What was the center of mass energy? Due Feb 12
Griffiths 4.8, 4.10, 4.13, 4.29, 4.30, 4.38. Also send by email your proposed paper topic. Due Feb 19
Griffiths 6.8,6.12, 6.14 (use results of problem 6.9, which you don’t have to do) + 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/m3 and the average neutrino-nucleon cross section = 8x10^-39 cm^2, what is the probability that the neutrino interacts in the block? Due Feb 26
Griffiths 7.6,7.13,7.18,7.48,7.49 (use your answer to 6.8 for part e). Also, send me (using email) an outline of your presentation (can just be a text file, but it should be a complete outline). Looking for roughly one item per slide, and remember that a good rule of thumb is one slide per minute (remember, it’s a 25 minute presentation) due March 23
Griffiths 8.17, 8.24. Also, draw the lowest order QCD diagrams for pp->2 jets. Finally, one important question for experimentalists: in what pT range are boosted topologies useful? For example, imagine a very high-pT, boosted W boson decaying to quarks. Show that the jet cone size containing the two quarks from its decay is roughly given by dR (really the cone diameter) roughly 2*mW / pT. Due April 6
Griffiths 9.5,9.16,9.29,9.30,9.31. Due April 20
