abstract

We show that testing Bell inequalities in $W^\pm$ pair systems by measuring their angular correlation suffers from the ambiguity in kinetical reconstruction of the di-lepton decay mode. We further propose a new set of Bell observables based on the measurement of the linear polarization of the $W$ bosons, providing a realistic observable to test Bell inequalities in $W^\pm$ pair systems for the first time.

  1. Qubit-qubit-qutrit quantum correlations in $H \to f \bar f V$

    quant-ph 2026-07 conditional novelty 7.0 of 10

    In h→τ^-τ^+ Z decays, the spin state is genuinely qubit-qubit-qutrit entangled almost everywhere, violates Bell inequalities throughout, and carries up to 1.95 bits of non-local magic.

  2. Quantum Tomography and Entanglement in Semi-Leptonic $h\to VV^*$ Decays at Higher Orders

    hep-ph 2026-04 unverdicted novelty 6.0 of 10

    Semi-leptonic h→VV* decays retain an effective two-qutrit quantum description under NLO QCD and electroweak corrections, unlike the fully leptonic h→4ℓ channel.

  3. Colliders are Testing neither Locality via Bell's Inequality nor Entanglement versus Non-Entanglement

    hep-ph 2025-07 conditional novelty 4.0 of 10

    Collider measurements of final-state momenta alone cannot certify Bell nonlocality or entanglement, because the measured angular distribution is itself a local hidden variable model.
