Abstract

We present new results for next-to-leading order (NLO) electroweak (EW) corrections to double polarization signals in the $WZ$ production channel at the LHC using the $e^+\nu_e \mu^+ \mu^-$ final state. It is found that the EW corrections are most sizable in the transverse momentum distributions of the doubly longitudinal polarization, being around -10% compared to the NLO QCD prediction at $p_{T,e}\approx 200$ GeV, which is in the accessible energy range of the current LHC data.
