How well can the LHC distinguish between the SM light Higgs scenario, a composite Higgs and the Higgsless case using VV scattering channels?

A complete parton level analysis of l(+)l(-) + four jets (l = e, mu) and 3l nu + two jets production at the LHC is presented, including all processes at order O(alpha(6)(EM)), O(alpha(4)(EM)alpha(2)(S)) and O(alpha(2)(EM)alpha(4)(S)) when appropriate. The infinite Higgs mass scenario, which is considered as a benchmark for strong scattering theories and is the limiting case for composite Higgs models, and one example of a model incorporating a Strongly Interacting Light Higgs are confronted with the Standard Model light Higgs predictions. This analysis is combined with the results in the l nu + four jets channel presented in a previous paper, in order to determine whether a composite Higgs signal can be detected as an excess of events in boson-boson scattering.
