Relativistic charge distributions of targets with arbitrary average momentum are introduced. They provide an interpolation between the usual Breit frame and infinite-momentum frame distributions. We find that Breit frame distributions can be interpreted from a phase-space perspective as internal charge quasi-densities in the rest frame of a localized target, without any relativistic correction. We show also that the apparent discrepancies between Breit frame and infinite-momentum frame distributions simply result from kinematical artifacts associated with spin.

    nucl-th 2026-02 conditional novelty 7.0

    First complete non-relativistic impulse-approximation calculation of all eleven deuteron EMT form factors, including non-conserved c-bar and s-bar form factors that map to force and torsion distributions inside the nucleons.

    hep-ph 2026-07 conditional novelty 6.0

    Radiative corrections to neutral-current (anti)neutrino-nucleon elastic scattering are computed within low-energy EFT and reach a few percent, comparable to the strange-quark effects they must be disentangled from.

    A modified non-separable LFWF ansatz for pseudoscalar heavy quarkonia enables computation of zero-skewness GPDs, EM and gravitational form factors, and transverse distributions within the Schwinger-function framework.

    hep-ph 2026-05 unverdicted novelty 5.0

    Nucleon EM form factors computed in instanton vacuum model with parameters fixed by saddle-point equation yield proton charge radius 0.841 fm matching muonic hydrogen and good agreement on Q2 dependence of ratios.

  9. Transverse energy-momentum tensor distributions in polarized nucleons

    hep-ph 2026-04 accept novelty 4.5

    Transverse EMT distributions in polarized nucleons are derived in the quantum phase-space formalism; they reduce to standard light-front densities (including bad components) in the infinite-momentum frame.
