Can someone give me a qualitative/handwaving argument of
why much more W^+/- boson are produced in proton-antiproton
collisions compared to Z^0 bosons?
PDFs are not enough to explain this I believe, since we will have more
u ubar pairs in the collision than u dbar...
Also if I remember correctly the coupling for the Z-2fermion
vertex is higher with a factor of 1/sin(theta_W). Well the vertices
are kinda different so this is not so simple.
Is there an easy way to guess this or one has to do a full LO calculation
or something?
