Description
Probing the electroweak sector and electroweak symmetry breaking in unprecedented detail is one of the primary goals of the upcoming HL-LHC program. Measurements of vector-boson polarizations represent a promising avenue toward this objective. The extraction of the different polarization components from experimentally accessible unpolarized distributions requires accurate particle-level polarization templates derived from Monte Carlo simulations.
Despite recent progress in the Powheg and Sherpa event generators, enabling full or approximate NLO QCD+PS calculations, a complete NLO QCD + NLO EW + PS description for arbitrary processes has not yet been achieved. In this talk, I will discuss ongoing developments in the Sherpa event generator toward automated fixed-order polarization predictions at NLO QCD + NLO EW - an essential step towards achieving this goal. In addition to these efforts, I will present the recent extension of Sherpa allowing for the modeling of polarized loop-induced processes at fixed leading order and matched to the parton shower, as well as report on the current status of an amplitude-assisted polarization tagger based on Sherpa predictions.
