Description
Vector Boson Scattering (VBS) has been identified as a promising process to study the nature of electroweak symmetry breaking. The best channel for VBS measurements is same-electric-charge W boson scattering: a rare Standard Model process that has a distinctive experimental signature of a same-electric-charge lepton pair and two high energy forward jets. The study of the electroweak production mechanism of W±W±jj scattering will continue through to the High-Luminosity Large Hadron Collider (HL-LHC) physics program. During this program, the HL-LHC will not only operate at an increased centre of mass energy of 14 TeV, but also produce an instantaneous luminosity of L = 7 × 1034 cm-2s-1. Several upgrades of various sub-detectors of the ATLAS detector are scheduled to cope with the intense radiation and the high pileup environment. The prospects for a W±W±jj measurement after the LHC and ATLAS detector upgrades will be discussed, with a focus on the impact of an extended tracking detector. The effect of the upgraded Inner Detector on the measurement for the same-electric-charge W±W± scattering process is evaluated by analysing simulated events with two leptons of the same electric charge, at least two jets and missing transverse energy.
