Abstract

We address momentum entanglement in Higgs decays to weak boson pairs, H→WW,ZZ, by discretizing momentum space. The momenta of the two weak bosons are entangled, as well as the degrees of freedom in momentum and spin spaces. For H→ZZ in the four-lepton final state, we also estimate the statistical sensitivity of entanglement measures at the Large Hadron Collider and future upgrades. The discretization method introduced here is broadly applicable, offering a framework for studies of momentum entanglement at the energy frontier.
