An Update on Strong $W_L W_L$ Scattering at the LHC

I summarize an update on our previous study (J. Bagger et al. Phys. Rev. D49, 1246) for a strongly interacting electroweak symmetry breaking sector via longitudinal vector boson scattering at the 14 TeV Large Hadron Collider. In the update, the decay mode $ZZ\to \ell^+\ell^- \nu \bar \nu$ and a new vector-resonance signal via $q\bar q' \to V \to W^+W^-/ W^\pm Z$ are also included.
