  We present results for the spectrum of a strongly interacting SU(3) gauge
theory with $N_f = 8$ light fermions in the fundamental representation.
Carrying out non-perturbative lattice calculations at the lightest masses and
largest volumes considered to date, we confirm the existence of a remarkably
light singlet scalar particle. We explore the rich resonance spectrum of the
8-flavor theory in the context of the search for new physics beyond the
standard model at the Large Hadron Collider (LHC). Connecting our results to
models of dynamical electroweak symmetry breaking, we estimate the vector
resonance mass to be about 2 TeV with a width of roughly 450 GeV, and predict
additional resonances with masses below ~3 TeV.
