VV-Fusion Process to Investigate EWSB; Interplay LC-LHC

Abstract

The VV -fusion is a promising process to investigate the electroweak symmetry breaking (EWSB) mechanism. In fact the cross section for the scattering of longitudinally polarized vector bosons, in absence of a Higgs, violates unitarity at about 1.2TeV. As a consequence, new physics must appear below this threshold. The LHC and the LC will be the machines which will explore the energy region where this new physics is expected. In the following the potential of the two accelerators for the study of this reaction is briefly reviewed and a preliminary study with the CMS detector at LHC is presented.
