摘要：

We use an effective lagrangian to study the leading corrections to WW-gamma and WWZ vertices from new, weak isospin conserving, heavy physics. The corrections occur in g1Z-1, k(Z)-1, and k(A)-1 and input from low energy QCD is used to estimate their size in technicolor theories. We then study the enhancement of these corrections in the process e+e- --> W+W- at high energies.
