Abstract

The comparison of the kinematic properties of different Vector Boson Scattering (VBS) and Vector Boson Fusion (VBF) processes using multivariate discriminator is presented. The search is performed to identify common features in the the polarized $W^{\pm}W^{\pm}jj$ channel, mainly central and forward region jets kinematic variables such as eta, phi, mass and transverse energy, in order to determine some universal cuts. Traditionally boosted decision trees (BDT) are used as multivariate discriminator. The presented results are based on proton-proton collision Monte Carlo (MC) simulation samples center-of-mass energy 14 TeV and corresponding to an integrated luminosity of 3000 $fb^{-1}$. MC samples are generated using MADGRAPH and PYTHIA.
