      abstract     = {We investigate the renormalization of the radiative decays
                      of the Higgs to two gauge bosons in the Standard Model
                      Effective Field Theory at mass dimension eight. Given that
                      these are loop-level processes, their one-loop
                      renormalization can be phenomenologically important when
                      triggered by operators generated through the tree-level
                      exchange of heavy particles (assuming a weakly coupled UV
                      model). By computing the tree-level matching conditions of
                      all relevant extensions of the Standard Model, we
                      demonstrate that this effect is indeed present in the $h\to
                      \gamma Z$ decay at dimension eight, even though it is absent
                      at dimension six. In contrast, the $h\to gg$ and $h\to
                      \gamma\gamma$ decays can only be renormalized by operators
                      generated by one-loop processes. For UV models with heavy
                      vectors, this conclusion hinges on the specific form of
                      their interaction with massless gauge bosons which is
                      required for perturbative unitarity. We study the
                      quantitative impact of the possible logarithmic enhancement
                      of $h\to \gamma Z$, and we propose an observable to boost
                      the sensitivity to this effect. Given the expected increased
                      precision of next-generation high-energy experiments, this
                      dimension-eight contribution could be large enough to be
                      probed and could therefore give valuable clues about new
                      physics by revealing some of its structural features
                      manifesting first at dimension eight.},
