Abstract

Under the assumption that the dijet excess seen by the CDF Collaboration near 150 Gev in Wjj production is due to the lightest technipion of the low-scale technicolor process ρTWπT\rho_T \rightarrow W \pi_T, we study its observability in LHC detectors with 1-5 fb^{-1} of data. We find that cuts similar to those employed by CDF are unlikely to confirm its signal. We propose cuts tailored to the LSTC hypothesis and its backgrounds at the LHC that can reveal πTjj\pi_T \rightarrow jj. We also stress the importance at the LHC of the isospin-related channel ρT±ZπT±jj\rho^{\pm}_T \rightarrow Z\pi^{\pm}_T \rightarrow \ell\ell jj and the all-lepton mode ρTpmWZ3+ν\rho^{pm}_T \rightarrow WZ \rightarrow 3\ell + \nu.
