Search for γγjj final states from Vector Boson Scattering at the ATLAS experiment — •Orcun Kolay — Technische Universität Dresden, Germany

Vector boson scattering (VBS) is a suitable process to observe triple and quartic gauge couplings. This rare processes provide us an avenue to examine electroweak (EW) symmetry breaking mechanism and to search for possible new physics effects. In this study, two photons along with two jets (γγjj) are taken into account as the final state. The measurement of the VBS γγjj process comes along with two main challenges as the background coming from QCD induced γγjj and misidentified jets as photon. In this talk, it will be presented an ongoing work which mainly covers the separation of EW γγjj from QCD γγjj, the signal-control region strategy for misidentified jets and the comparison of the different Monte Carlo event generators for the signal phase space.
