### Description

Operators with the vertex $h Z_{\mu \nu} h Z^{\mu \nu}$ contributing to associated production of a Higgs boson with a transverse Z boson, do not interfere with the dominant longitudinal part of the $Zh$ amplitude at high energies. Here we explore how angular distributions related to the Z decay products can be used to recover the interference term and thus gain sensitivity to these operators.
