abstract

We propose a theory that preserves spin-summed scattering and decay rates at tree level while affecting particle spins. This is achieved by breaking the Lorentz group in a non-local way that tries avoiding stringent constraints, for example leaving unbroken the maximal sub-group SIM(2). As a phenomenological application, this new physics can alter the spins of top-antitop pairs (and consequently their entanglement) produced in $pp$ collisions without impacting their rates. Some observables affected by loops involving top quarks with modified entanglement receive corrections.

  1. Entanglement, Yang-Mills, and the Scattering Matrix as an SU(N)-equivariant Kernel

    hep-ph 2025-11 conditional novelty 6.0 of 10

    SU(N) symmetry fixes the entangling power of 2→2 scattering: Yang-Mills adjoint scattering has a group-only entanglement maximum at 90° (3/4 for SU(2), ≈0.91 for SU(3)), and maximal-entanglement preservation selects t...

  2. Measuring Quantum Discord at the LHC

    hep-ph 2024-12 conditional novelty 6.0 of 10

    The authors derive closed-form formulas for quantum discord in the ttbar system and predict it can be measured at the LHC with sub-percent precision using the kinematic method.
