The Electroweak Chiral Lagrangian and CP-Violating Effects in Technicolor Theories

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 $t\to b+W^{+}$.
