Description
Angular correlations in Higgs decays to electroweak gauge bosons, $h \to ZZ^*,WW^*$, provide a powerful probe of both new physics effects and quantum information observables. At leading order, the system admits an effective two-qutrit description, yielding entangled states across the entire kinematic spectrum. We show that next-to-leading order electroweak corrections introduce significant modifications to the angular observables that challenge the two-qutrit interpretation in the $h \to e^+e^-\mu^+\mu^-$ channel, while the $h \to WW^*$ channel remains comparatively robust.
