Checklist for VL-03:

slides 6:

(1)
The Fermi constant GF is defined as GF=sqrt(2)/8*g**2/mW**2 where g**2 is the 
coupling constant of the non-Abelian Gauge as introduced in VL02. See aso 
checklist question (6) and slide 23 of VL02. Do you understand how GF emerges 
from the propagator for W boson exchange in the SM?

slides 7f: 

(2)
Do you understand how the additional amplitudes introduced by the Gauge boson 
exchanges can cure the divergencies discussed in this and the following slide? 

slide 9:

(3)
Do you know how a magnetic horn works?
