1) Draw and explain shape of the cross-section for e+ e- --> f anti-f as function
of the sqrt(s) of incoming electron beams, in the range from gew GeV to 200 GeV. 
(starting point should be page 62 of the lecture and then go back to pick details)

2) Could you explain measurement of the W and Z cross-section at LHC.
What are steps of such measurement? How the error on the theoretical predictions 
and performance of the detector is accounted for. How the theoretical predictions
enter as cmponent of the measurement?
