Low-scale technicolor at the Tevatron and LHC

Abstract

The Tevatron experiments CDF and DØ are close to making definitive statements about the technicolor discovery mode 𝘱𝘛 ⟶ 𝘞𝜋𝘛 for 𝘔𝜋𝘛 ≲ 250GeV and 𝘔𝜋𝘛 ≲ 150GeV. We propose new incisive tests for this mode and searches for others that may be feasible at the Tevatron and certainly are at the LHC. The other searches include two long discussed, namely, ω𝘛 ⟶ 𝛾𝜋𝘛 and 𝓁^+𝓁^-, and a new one—for the 𝐼^𝐺𝘑^𝘗𝘊 ＝ 1^-1^++ partner, 𝛼𝘛, of the 𝘱𝘛. Adopting the argument that the technicolor contribution to S is reduced if 𝘔𝛼𝘛 ≃ 𝘔𝘱𝘛, we enumerate important 𝛼𝘛 decays and estimate production rates at the colliders.
