Abstract:

We estimate the CP-violating

WW\gamma

and

WWZ

anomalous form factors, arising from CP-violating interactions in extended technicolor theories, and discuss their future experimental detectability. The electric dipole moment of the

W

boson is found to be as large as {\cal O}(10~{-21}) \; \mbox{$e$ cm}. We connect the CP-odd

WW\gamma

and

WWZ

couplings to the corresponding CP-violating electroweak chiral lagrangian operators. The electric dipole moments of the neutron and the electron in technicolor theories are estimated to be as large as {\cal O}(10~{-26}) \; \mbox{$e$ cm} and {\cal O}(10~{-29}) \; \mbox{$e$ cm} respectively. We also suggest the potential to observe large CP-violating technicolor effects in the decay
