WW scattering in walking technicolor: No discovery scenarios at the CERN LHC and ILC

We analyze the WW scattering in scenarios of dynamical electroweak symmetry breaking of walking technicolor type. We show that in these theories there are large regions of the parameters space allowed by the electroweak precision data, in which unitarity is delayed at tree level up to around 3-4 TeV without the inclusion of any sub-TeV resonances. If any of these scenarios is actually realized then the new physical states are not within reach of the LHC and International Linear Collider. © 2008 The American Physical Society.
