Summary

In this talk I will analyze the associated production of Higgs and Z boson via heavy-quark
loops at the LHC in the Standard Model and beyond. After briefly talking about the main
features of the born 2 to 2 production, I will consider the effects of extra QCD radiation. I
will show how merged samples of 0 and 1 jet multiplicities matched to a parton shower can
provide a reliable description of differential distributions in ZH production. In addition
to the SM case, results in a generic 2HDM will be shown for a set of representative and
experimentally viable benchmarks for both the scalar and pseudoscalar cases. I will finally
conclude by discussing the interesting features coming from the resonant enhancement and
interference patterns between resonant and non-resonant contributions.
