In multiscale models of walking technicolor, relatively light color-singlet technipions are produced in annihilation in association with longitudinal W and Z bosons and with each other. The technipions decay as 𝜋T^0 ⟶ bb and 𝜋T^+ ⟶ cb. Their production rates are resonantly enhanced by isovector technirho vector mesons with mass Mw + MπT ≲ MϱT ≲ 2MπT. At the Tevatron, these associated production rates are 1–10 picobarns for M𝜋T ≲ 100 GeV . Such a low mass technipion requires topcolor-assisted technicolor to suppress the decay t → πT^+b. Searches for πTπT production will also be rewarding. Sizable rates are expected if MϱT≳ 2MπT + 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 → γπT^0 and ZπT^0.
