摘要
Precision electroweak data, a light Higgs boson and LHC searches for new spin one particles are all very constraining on technicolor models. We use a holographic model of walking technicolor gauge dynamics, tuned to produce a light Higgs boson and low S parameter, to estimate the range of possible vector(p) and pseudovector(A) resonance masses and couplings as a function of the number of colors and the number of flavors of technisinglet and technidoublet quarks. The resulting models predict technihadron masses and couplings above the current limits from dilepton resonance searches at the LHC because their masses are enhanced by the strong coupling extending into the multi-TeV range, while couplings to Standard Model fermions are partly suppressed. The models emphasize the contortions needed to continue to realize technicolor, the need to explore new signatures beyond dilepton for LHC and also motivate a 100 TeV proton collider.
