Abstract
In this dissertation we look into the vector boson scattering process in the semi-leptonic channel using 20.2 $fb^{−1}$ of 2012 proton-proton collision data at $\sqrt{s}$ = 8 TeV coming from the Large Hadron Collider. The final state considered is WVjj (V=W,Z) where the W decays into a charged lepton (electron or muon) and a neutrino and the other vector boson decays hadronically. The analysis requires one charged lepton, missing transverse energy and four jets, two of which are forward jets with a large invariant mass. Expected limits on the anomalous quartic gauge coupling (aQGC) parameters were estimated using Whizard+Pythia8 Monte Carlo samples for signal. The observed limits on the aQGC coefficients $\alpha_{4}$ and $\alpha_{5}$ are [−0.030, 0.034] and [−0.033, 0.038] respectively at 95% confidence level. | In this dissertation we look into the vector boson scattering process in the semi-leptonic channel using 20.2 $fb^{−1}$ of 2012 proton-proton collision data at $\sqrt{s}$ = 8 TeV coming from the Large Hadron Collider.
