Enhancing the doubly-longitudinal polarization in W Z production at the LHC

We present new results for the theoretical prediction of doubly-polarized cross sections of W Z events at the LHC using leptonic decays. Compared to the previous studies, two new kinematic cuts are considered. These cuts are designed to enhance the doubly-longitudinal (LL) polarization and, at the same time, study the Radiation Amplitude Zero effect.
