Description
Gluon-induced production of a Higgs boson in association with a Z-boson is an important Higgs production channel at the LHC. Precise theoretical predictions for this channel are therefore required, both within the Standard Model and beyond. Effects beyond the SM can be parametrised using the Standard Model Effective Field Theory (SMEFT).
In this talk, we present the NLO QCD predictions for $gg \to ZH$ including fully analytic top-mass-dependence. We incorporate the leading dimension-six SMEFT operators relevant for this process. We study their phenomenological impact and the interplay of the Wilson coefficients, based on an implementation in Powheg-Box-V2.
