摘要
We discuss the production and decay rates of the lightest color-singlet technihadrons, spin-one rho(T) and omega(T) and spin-zero pi(T) in a minimal "straw-man" model of low-scale technicolor. Because of walking technicolor enhancements of technipion masses, the decay channels rho(T)-->pi(T)pi(T) and omega(T)-->pi(T)pi(T)pi(T) are likely to be closed. The largest decay modes then are rho(T)-->W pi(T), gamma pi(T) and omega(T)-->gamma pi(T), while rho(T), omega(T)-->l(+)l(-) offer low-rate but very clear signatures. The revised rho(T) and omega(T) decay rates to gamma pi(T) presented here affect the technicolor searches planned for run II of the Fermilab Tevatron collider. [S0556-2821(99)00919-4].
