Twist-2 relation and sum rule for tensor-polarized parton distribution functions of spin-1 hadrons

Journal of High Energy Physics, 2021
Sum rules for structure functions and their twist-2 relations have important roles in constraining their magnitudes and x dependencies and in studying higher-twist effects. The Wandzura-Wilczek (WW) relation and the Burkhardt-Cottingham (BC) sum rule are

Photon–jet correlations in deep-inelastic scattering

European Physical Journal C: Particles and Fields, 2017
The reaction $$e + p \rightarrow \gamma + \mathrm{jet} + X$$ e + p → γ + jet + X is studied in QCD at the next-to-leading order. Previous studies on inclusive distributions showed good agreement with ZEUS data.

Novel corrections to the momentum sum rule for nuclear structure functions

Physics Letters B, 2022
We address novel features of deep inelastic lepton scattering on nuclei at small Bjorken variable xBj. In this regime the lepton-nuclear cross section involves the interference between the standard lepton-quark scattering amplitude for the deep inelastic

Neutron Valence Structure from Nuclear Deep Inelastic Scattering. [PDF]

Physical Review Letters, 2019
Mechanisms of spin-flavor SU(6) symmetry breaking in quantum chromodynamics (QCD) are studied via an extraction of the free neutron structure function from a global analysis of deep inelastic scattering (DIS) data on the proton and on nuclei from A=2 ...

Collins and Sivers transverse-spin asymmetries in inclusive muoproduction of ρ0 mesons

Physics Letters B, 2023
The production of vector mesons in deep inelastic scattering is an interesting yet scarcely explored channel to study the transverse spin structure of the nucleon and the spin-dependence of fragmentation. The COMPASS collaboration has performed the first

Tensor Pomeron and low- x deep inelastic scattering [PDF]

Physical Review D, 2019
The tensor-pomeron model is applied to low-x deep-inelastic lepton-nucleon scattering and photoproduction. We consider c.m. energies in the range 6 - 318 GeV and Q^2 < 50 GeV^2.
