Low-Scale Technicolor at the Tevatron and LHC

Abstract

The Tevatron experiments CDF and DO are close to making definitive statements about the technicolor discovery mode rho_T -> W pi_T for M(rho_T) <~ 230 GeV and M(pi_T) <~ 125 GeV. 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, omega_T -> gamma pi_T and l+l-, and a new one -- for the I^G J^{PC} = 1^- 1^{++} partner, a_T, of the rho_T. Adopting the argument that the technicolor contribution to S is reduced if M(a_T) is near M(rho_T), we enumerate important a_T decays and estimate production rates at the colliders.

Version to be published in Physics Letters B. Revised to reflect latest CDF search for technirho to W technipi and new studies of the LHC's reach for low-scale technicolor
