There are two possibilities for electroweak symmetry breaking: either there is a scalar particle much lighter than 1 TeV or the longitudinal components of W and Z bosons interact strongly at center of mass energies of order 1 TeV or more. We study the general signatures of a strongly interacting W, Z system and conclude that these two possibilities can be unambiguously distinguished by a hadron collider facility capable of observing the enhanced production of WW, W Z and Z Z pairs that will occur if W's and Z's have strong interactions. Detection of the enhanced signal over background requires hadron collisions at a center of mass energy of order .;s = 40 TeV and an integrated luminosity of order 10· 0 cm-2 • With these parameters we predict 3800 to 6000 gauge boson pairs satisfying cuts for which only 2600 pairs would be produced in the absence of strong interactions.As our results draw on the global chiral SU(2) symmetry of the scalar sector of the standard SU(2) X U(1) model, we give an extended proof, to all orders in the generalized renormalizable gauge, that high energy amplitudes of longitudinal W's and Z's are well approximated by amplitudes of the corresponding unphysical scalars. The results are applicable to the broad class of strong interaction models that admit a global chiral SU(2) symmetry.2
