We present a unified analysis of the two main production processes of vectorboson pairs at the LHC, VV-fusion and qqbar annihilation, in a minimal stronglyinteracting electroweak symmetry breaking sector. Using a unitarizedelectroweak chiral Lagrangian formalism and modeling the final V_L V_L strongrescattering effects by a form factor, we describe qqbar annihilation processesin terms of the two chiral parameters that govern elastic V_L V_L scattering.Depending on the values of these two chiral parameters, the unitarizedamplitudes may present resonant enhancements in different angularmomentum-isospin channels. Scanning this two parameter space, we generate thegeneral resonance spectrum of a minimal strongly interacting electroweaksymmetry breaking sector and determine the regions that can be probed at theLHC.Comment: Final version to appear in Phys. Rev. D, including a more detailed exposition and a few more references. Conclusions and results unchanged. 14 pages, 5 figure
