The quark-parton model calculation including the effects of intrinsic transverse momentum and of all six twist-two distribution functions of quarks in polarized nucleons is performed. It is demonstrated that new twist-two quark distribution functions and polarized quark fragmentation functions can be investigated in semi-inclusive DIS at leading order in $Q^2$. The general expression for the cross-section of semi-inclusive DIS of polarized leptons on polarized nucleons in terms of structure functions is also discussed.

  1. Next-to-next-to-leading power corrections to unpolarized Semi-Inclusive Deep Inelastic Scattering

    hep-ph 2026-01 conditional novelty 6.0

    Analytic 1/Q² corrections to the four unpolarized SIDIS structure functions are derived from the rapidity-factorization 'gauge-completion' approach, giving f1⊗D1 and h1^⊥⊗H1^⊥ convolutions with numerical estimates for...

    hep-ph 2025-12 conditional novelty 6.0

    OPEC in e+A collisions factorizes in TMD QCD and predicts ~0.3–0.4 nuclear suppression at small angles, growing with angle, as a probe of cold-nuclear-matter broadening.

  3. Collins asymmetries for pion-in-jet production in polarized $\ell p$ collisions at the EIC

    hep-ph 2026-05 unverdicted novelty 4.0

    Collins asymmetries for pion-in-jet production in polarized lepton-proton collisions provide clearer access to transversity distributions at the EIC and test the universality of the Collins function.

  4. Collins asymmetries for pion-in-jet production in polarized $\ell p$ collisions at the EIC

    hep-ph 2026-05 unverdicted novelty 4.0

    Collins asymmetries for pion-in-jet production at the EIC are calculated in LO and Weizsacker-Williams approximations, showing quark-channel dominance and clearer access to sea-quark transversity.

  5. Applications of the WW-type approximation to SIDIS

    hep-ph 2019-07 unverdicted novelty 4.0

    Applies the WW-type approximation to relate TMDs and FFs and approximate the complete SIDIS cross-section up to power-suppressed terms.
