Low-Scale Technicolor at the Tevatron and LHC

TL;DR

This paper discusses the potential for discovering low-scale technicolor particles at the Tevatron and LHC, proposing new tests and searches for technicolor resonances like rho_T, pi_T, omega_T, and a_T.

Contribution

It introduces new experimental tests and search strategies for technicolor particles, including a novel search for the a_T resonance, and estimates their production rates at colliders.

Findings

Tevatron experiments are close to confirming technicolor signals for certain mass ranges.

Proposed new tests could improve detection sensitivity for technicolor resonances.

Estimated production rates suggest feasible detection at the 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.
