Higgs Pseudo Observables and Radiative Corrections

Abstract

We show how leading radiative corrections can be implemented in the general description of $h\to 4\ell$ decays by means of Pseudo Observables (PO). With the inclusion of such corrections, the PO description of $h\to 4\ell$ 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 $h\to 2e2\mu$ dilepton mass spectrum is recovered within 1% accuracy. The impact of radiative corrections for non-standard PO is also briefly discussed.
