  If electro-weak symmetry is broken by a new strongly interacting sector, new
physics will probably manifest itself in gauge boson scattering at the LHC. The
relevant dynamics is well described in terms of an effective lagrangian. We
discuss the probable size of the coefficients of the relevant operators under a
combination of model-independent constraints and reasonable assumptions based
on two models of the strongly interacting sector. We compare these values with
LHC sensitivity and argue that they will be too small to be seen. Therefore,
the presence of vector and scalar resonances required by unitarity will be the
only characteristic signature. We analyze the most likely masses and widths of
these resonances.
