Description

LHC data and phenomenological estimates agree that polarization interference is inherently small for multiboson production at the LHC. In this talk, we show that this could be understood from kinematical arguments and angular momentum conservation, and is a non-trivial consequence of the (near) masslessness of initial- and final-state fermions coupling to intermediate, helicity-polarized weak bosons. We finish we a brief comment on minor adjustments to search strategies can lead to more robust/stable definitions of polarization across different classes of gauge fixing.
