01.10.18 Exercises on this course are done in pairs. Find yourself an exercise partner. If you can't find anyone, send me an email @cern.ch. Ps. Exercise points are collected only by being ready to present your solutions/work on the blackboard. -MM

Questions?

Exercise 24.10: There was a typo (1/2 instead of -) in the exercise sheet (pseudorapidity formula).

Exercise 17.10: A high-tech question about Green's functions and vacuum expectation values. A suitable reference might be this classic paper by Wightman: https://journals.aps.org/pr/abstract/10.1103/PhysRev.101.860

E/17:10: Some questions about SU(2), SO(3) and (half)-integer spin. Simple answer, integer spin particles (bosons) pick no multiplicative minus sign (-1) under 2π rotations, half integer particles do. This is the 'physical reason' why SO(3) is enough only for 3D-rotations, and for fermion (spinor) type phenomena we need SU(2).
