Boson-boson scattering and Higgs production at the LHC from a six fermion point of view: four jets + l$\nu$ processes at $Ø({\alpha }_{em}^6)$

Abstract

Boson-boson scattering and Higgs production in boson-boson fusion hold the key to electroweak symmetry breaking. In order to analyze these essential features of the Standard Model we have performed a partonic level study of all processes $q_1{q}_2\to q_3{q}_4{q}_5{q}_{6}l\nu$ at the LHC using the exact matrix elements at $Ø({\alpha }_{em}^6)$ provided by \Phase, a new MC generator. These processes include also three boson production and the purely electroweak contribution to \toptop production as well as all irreducible backgrounds. Kinematical cuts have been studied in order to enhance the VV scattering signal over background. \Phase has been compared with different Monte Carlo's showing that a complete calculation is necessary for a correct description of the process.
