Electroweak $W^{\pm}W^{\pm}jj$ Production in ATLAS

Vector boson scattering is one of the recent remarkable observations at the Large Hadron Collider. The longitudinal polarization modes of the massive vector bosons are strongly tied to the electroweak symmetry breaking mechanism. With the Standard Model predicted Higgs boson playing a crucial role in regularizing the scattering amplitude of these longitudinally polarized bosons, vector boson scattering is a pivotal process in experimentally probing the symmetry breaking mechanism. A golden channel for measuring vector boson scattering at the collider is the electroweak production of two $W$ bosons with the same electric charges. This report presents the measurement of $W^{\pm}W^{\pm}jj$ production cross-sections using Run 2 proton-proton collisions at $\sqrt{s}$ = 13 TeV with the ATLAS experiment.
