# W and Z boson production and decay at e-e+ collider

Hi!

I was wondering how W+/- pairs can be created in an electron/positron collider.

Does the e+e- form a $Z^0$ which decays to $W^- W^+$ ?

I have found this picture, but there is no info about the mediating particle (in the small feynman diagram to the right) and I have looked in my two books about particle physics, and on wikipedia. and have not found any information at all

The books I have considered are "particle physics" by Martin & Shaw, and "Particles and nuclei" by Povh et. al.

EDIT: Is it also possible for the $W^- W^+$ to be created from an intermediate photon?

Thank you for your time and help :-)
