The process gg->WW as a probe into the EWSB mechanism

Understand

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.
