Abstract

We estimate the CP-violating WWγWW\gamma and WWZWWZ anomalous form factors, arising from CP-violating interactions in extended technicolor theories, and discuss their future experimental detectability. The electric dipole moment of the WW boson is found to be as large as {\cal O}(10^{-21}) \; \mbox{e cm}. We connect the CP-odd WWγWW\gamma and WWZWWZ 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 tb+W+t \rightarrow b + W^+.
