Low-scale technicolor at the Tevatron

In multiscale models of walking technicolor, relatively light color-singlet technipions are produced in q overlineq annihilation in association with longitudinal W and Z bosons and with each other. The technipions decay as π _T⁰ → b overlineb and π _T⁺ → c overlineb. Their production rates are resonantly enhanced by isovector technirho vector mesons with mass M_W + M_πT ≲ M_ϱT ≲ 2 M_πT. At the Tevatron, these associated production rates are 1-10 picobarns for M _πT ⋍ 100 GeV. Such a low mass technipion requires topcolor-assisted technicolor to suppress the decay t → π_T⁺b. Searches for πTπT production will also be rewarding. Sizable rates are expected if M_ϱT ≳ 2 M_πT + 10 GeV. The isoscalar ωT is nearly degenerate with ϱT and is expected to be produced at roughly the same rate. The ωT should have the distinctive decay modes ωT → γπ _T⁰ and Zπ_T⁰.
