摘要：
Current LEP data on rare Z decays constrain nonminimal technicolor models that contain light neutral pseudo-Nambu-Goldstone bosons (P-a). We discuss the production and decay of such particles, and show how LEP data on gamma gamma gamma, gamma + E and gamma+hadrons constrain the size of the technicolor gauge group and the strength of the Z gamma P-a coupling. The limits are then applied to several specific technicolor scenarios.
