Polarized vector boson scattering in the fully leptonic WZ and ZZ channels at the LHC

Understand

Isolating the scattering of longitudinal weak bosons at the LHC is an important tool to probe the ElectroWeak Symmetry Breaking mechanism.

• Separating polarizations of $W$ and $Z$ bosons is complicated, because of non resonant contributions and interference effects.
• Additional care is necessary when considering $Z$ bosons, due to the $\gamma/Z$ mixing in the coupling to charged leptons.
• We propose a method to define polarized signals in $Z\!Z$ and $W^+\!Z$ scattering at the LHC, which relies on the separation of weak boson polarizations at the amplitude level in Monte Carlo simulations.
