Different polarization definitions in same-sign $WW$ scattering at the LHC

High Energy Physics - Phenomenology 2020-12-02 v2 High Energy Physics - Experiment

Abstract

We study the polarization of positively charged WW's in the scattering of massive electroweak bosons at hadron colliders. We rely on the separation of weak boson polarizations in the gauge-invariant, doubly-resonant part of the amplitude in Monte Carlo simulations. Polarizations depend on the reference frame in which they are defined. We discuss the change in polarization fractions and in kinematic distributions arising from defining polarization vectors in two different reference frames which have been employed in recent experimental analyses.
