Abstract

We present the first estimate of the gluon-gluon fusion process, gg->4f, in the high energy domain as a probe of the electroweak symmetry breaking mechanism (EWSB). We consider the exact matrix element at $O(\alpha_s\alpha_{em}^2)$, and we include all irreducible background coming from qq->4f. Purely leptonic final states, pp->llvv, are numerically investigated. We find that this channel is extremely sensitive to the regime of the interaction between gauge bosons. It can thus be associated to the traditionally used vector boson scattering (VBS) to improve the analysis of the EWSB physics.
