EFT Validity Issues in aQGC Analysis of Same-Sign $\textrm{WW}$ Scattering Process

Vector Boson Scattering (VBS) processes are regarded as the best laboratory to study the anomalous quartic gauge couplings. Such studies are carried out in the framework of effective field theory (EFT). However, the EFT formalism is often not used in a fully consistent way. In this contribution, we present an analysis of anomalous quartic gauge couplings in WW scattering processes at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector. The “Clipping” technique is implemented for data analysis in the EFT language.
