B-B Mixing in Dynimically Broken Theory

The B_d-B_d mixing is investigated in a dynamically broken electroweak theory such as the minimal technicolor theory with a monophagic coupling of quarks and pseudo-Goldstone bosons. The contrbutions of the technicolor pseudo-Goldstone bosons, enhanced by QCD color fowors, dominate the process for a wide range of parameters. If the topdown quark Kobayashi-Maskawa matrix element is not near the minimal allowed value, the pseudo-Goldstone bosone plus W boson can adequately account for the observed mixing large of the pseudo-Goldstone boson and top quark mass.
