We will discuss the role of the Higgs boson in the regularization of processes involving weak bosons. We will focus mainly on vector boson scattering and recent results at the LHC, but also exemplify other processes where divergencies occur, and where the role of the Higgs boson in restoring unitarity can be looked at. We will finally discuss prospects for this physics at future colliders.
o Biography
Dr Claude Charlot has been working on heavy ion collisions with the first heavy ion beams at CERN. He then worked in CMS experiment at the LHC, as a member of one of the founding laboratories of the experiment, and contributed to the construction of the electromagnetic calorimeter. His physics interest was focused on the Higgs boson search, in particular in the H->ZZ->4l channel, for which he contributed to the first algorithms for the reconstruction and identification of electrons. He was a member of the Higgs coordination group at the time of the discovery, and after that contributed to several measurements of the Higgs boson properties, in particular the Higgs width from the off-shell production. Since then, he has been working on vector boson scattering as another way to look at Higgs boson properties. He is now working also on di-Higgs measurement and on the preparation of the upgrade for HL-LHC.
