The present study focuses on Vector Boson Scattering (VBS) processes, which offer valuable insights into the Quartic Gauge Couplings (QGCs). While the Standard Model allows self-interactions of charged vector gauge bosons, interactions involving only neutral bosons are prohibited. The analysis utilizes Monte Carlo (MC) samples containing VBS events featuring two Z-bosons in association with two jets in the final state. The objective is to estimate the constraints on dimension-8 Effective Field Theory coefficients for the \(\mathcal {O}_{T,j}\) operators in the ZZjj channel at proton-proton collisions at center-of-mass energy of 13 TeV, using data of an integrated luminosity of 139 f \(b^{-1}\) . To mimic the geometry of the ATLAS detector, fully reconstructed MC samples with final-state configurations of 4 leptons and 2 jets are employed. This preliminary study paves the way for further analysis and provides valuable information on the behavior of QGCs in VBS processes.

摘要

The present study focuses on Vector Boson Scattering (VBS) processes, which offer valuable insights into the Quartic Gauge Couplings (QGCs). While the Standard Model allows self-interactions of charged vector gauge bosons, interactions involving only neutral bosons are prohibited. The analysis utilizes Monte Carlo (MC) samples containing VBS events featuring two Z-bosons in association with two jets in the final state. The objective is to estimate the constraints on dimension-8 Effective Field Theory coefficients for the \(\mathcal {O}_{T,j}\) operators in the ZZjj channel at proton-proton collisions at center-of-mass energy of 13 TeV, using data of an integrated luminosity of 139 f \(b^{-1}\) . To mimic the geometry of the ATLAS detector, fully reconstructed MC samples with final-state configurations of 4 leptons and 2 jets are employed. This preliminary study paves the way for further analysis and provides valuable information on the behavior of QGCs in VBS processes.
