We study the role of purely external kinematical approximations in inclusive deep-inelastic lepton--hadron scattering within QCD factorization, and consider factorization with an exact treatment of the target hadron mass. We discuss how an observed phenomenological improvement obtained by accounting for target mass kinematics could be interpreted in terms of general properties of target structure, and argue that such an improvement implies a hierarchy of nonperturbative scales within the hadron.

  1. Impact of parity-violating deep-inelastic scattering on the weak mixing angle and high-$x$ parton distributions

    hep-ph 2026-06 unverdicted novelty 4.0

    Simulations of 11 and 22 GeV PVDIS pseudodata indicate potential constraints on low-Q² sin²θ_W and high-x strange quark and d/u PDFs, with strong correlations requiring simultaneous QCD-electroweak analysis.

  2. Stability of parton distributions at high $x$: impact of nuclear and power corrections

    hep-ph 2026-05 unverdicted novelty 4.0

    Global fit finds u and d PDFs stable to x≈0.8 with positive isospin-independent higher-twist corrections and nonzero off-shell nucleon contributions required to describe nuclear data.
