Electro-Weak Physics in e+ e- Interactions

At the core of our present understanding of weak interactions is the mediation of the weak force between two point-like fermions via a weak intermediate vector boson, W+- or Z0 with vector and axial vector couplings whose strength may depend on the type(s) of fermions. Electron-positron collisions provide a particularly clean way to study the nature of these fundamental constituents of matter and their interactions because of the point-like nature of leptons. Experiments here are free of the complications that arise in studies of hadron-hadron or lepton-hadron collisions, where the hadrons themselves have a complex internal structure which must be understood in detail before new information on the large q2 interactions of the constituents can be extracted. Therefore e+e- collisions at high CM energies can be directly used to probe the very fundamental questions in weak interactions, e. g., how many quarks and leptons are there? Are there additional weak bosons with mass below that predicted by the standard models? How large are the weak interaction coupling constants?
