The $η_6$, a ``heavy axion'' associated with sextet quark electroweak symmetry breaking, may have been seen at LEP via its two-photon decay mode and also at TRISTAN via its hadronic decay modes. - presented at DPF 92.
We present the minimal sextet--quark condensation model as an attractive alternative to the standard model. The model is constructed by a simple and natural extension beyond the standard model and has many new interesting features some of which can be tested readily at the existing colliders. A crucial test may be a short--lived axion-- like $η_6$ of mass 30--60 GeV, which can produce high energy photons diffractively at hadron colliders and radiatively in $e^+ e^-$ colliders.
