We show how leading radiative corrections can be implemented in the general description of h→4ℓ decays by means of Pseudo Observables (PO). With the inclusion of such corrections, the PO description of h→4ℓ decays can be matched to next-to-leading-order electroweak calculations both within and beyond the Standard Model (SM). In particular, we demonstrate that with the inclusion of such corrections the complete next-to-leading-order Standard Model prediction for the h→2e2μ dilepton mass spectrum is recovered within 1% accuracy. The impact of radiative corrections for non-standard PO is also briefly discussed.
