Vector Boson Scattering Processes: Status and Prospects
Diogo Buarque Franzosi, Michele Gallinaro, Richard Ruiz +26
Insight into the electroweak (EW) and Higgs sectors can be achieved through measurements of vector boson scattering (VBS) processes. The scattering of EW bosons are rare processes…
SM EFT effects in Vector-Boson Scattering at the LHC
Athanasios Dedes, Paweł Kozów, Michał Szleper
The assumption that the Standard Model is an Effective Field Theory (SM EFT) of a more fundamental theory at a higher, than electroweak, energy scale, implies a growth of cross-sec…
Beyond the Standard Model in Vector Boson Scattering Signatures
Michele Gallinaro, Kenneth Long, Jürgen Reuter +19
The high-energy scattering of massive electroweak bosons, known as vector boson scattering (VBS), is a sensitive probe of new physics. VBS signatures will be thoroughly and systema…

We investigate the Beyond Standard Model discovery potential in the framework of the Effective Field Theory (EFT) for the same-sign scattering process in purely leptonic d…
Same-sign WW Scattering in the HEFT: Discoverability vs. EFT Validity
P. Kozow, L. Merlo, S. Pokorski +1
Vector boson scatterings are fundamental processes to shed light on the nature of the electroweak symmetry breaking mechanism. Deviations from the Standard Model predictions on the…
Same-sign WW scattering at the LHC: can we discover BSM effects before discovering new states?
Jan Kalinowski, Paweł Kozów, Stefan Pokorski +3
It is possible that measurements of vector boson scattering (VBS) at the LHC will reveal disagreement with Standard Model predictions, but no new particles will be observed directl…
