We specify recursive equations that could be used to generate a lowest order parton shower for hard scattering in hadron-hadron collisions. The formalism is based on the factorization soft and collinear interactions from relatively harder interactions in QCD amplitudes. It incorporates quantum interference between different amplitudes in those cases in which the interference diagrams have leading soft or collinear singularities. It incorporates the color and spin information carried by partons emerging from a hard interaction. One motivation for this work is to have a method that can naturally cooperate with next-to-leading order calculations.

  1. Polarization interference in exclusive $V+$jets at all orders in $\alpha_s$

    hep-ph 2026-06 unverdicted novelty 7.0

    Polarization interference in γ*→ℓ+ℓ− vanishes after lepton integration in exclusive V+jets at all α_s orders, with softened cancellations for W/Z due to parity violation and a formula for fiducial cuts.

  2. Decoherence effects in entangled fermion pairs at colliders

    Calculates decoherence from radiation on a Bell-state fermion pair by mapping integrated Altarelli-Parisi splitting functions to Kraus operators of an open quantum system.
