A new approach to semi-inclusive deep-inelastic scattering with QED and QCD factorization

Journal of High Energy Physics, 2021
We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent

A New Fracture Function Approach to QCD Initial State Radiation [PDF]

, 2007
Ordinary fracture functions, describing hadrons production in the deep inelastic scattering target fragmentation region, are generalized to account for the production of hadrons in arbitrary number, thus offering a renewed framework for dealing with QCD ...

Soft corrections to inclusive deep-inelastic scattering at four loops and beyond

Journal of High Energy Physics, 2020
We study the threshold corrections for inclusive deep-inelastic scattering (DIS) and their all-order resummation. Using recent results for the QCD form factor, related anomalous dimensions and Mellin moments of DIS structure functions at four loops we ...

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

Lorentz and CPT violation in partons

Journal of High Energy Physics, 2020
A framework is presented for the factorization of high-energy hadronic processes in the presence of Lorentz and CPT violation. The comprehensive effective field theory describing Lorentz and CPT violation, the Standard-Model Extension, is used to ...

Deep Inelastic Scattering

, 1995
In Sect. 5.5 we discussed the spectra observed in electron scattering off nuclei. As well as the elastic scattering peak some additional peaks, which we associated with nuclear excitations, were observed. Similar spectra are observed for electron-nucleon scattering.

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 Structure Function and A=3 Mirror Nuclei [PDF]

, 2000
We investigate deep inelastic scattering from He-3 and H-3 within a conventional convolution treatment of binding and Fermi motion effects. Using realistic Faddeev wave functions together with a nucleon spectral function, we demonstrate that the free ...

Perspectives of Semi-Inclusive Deep-Inelastic Scattering [PDF]

EPJ Web of Conferences
This contribution highlights some topics addressed by current and future experiments in Semi-Inclusive Deep-Inelastic Scattering. We concentrate on the programs at 12 and 22 GeV at Jefferson Lab using the CLAS detector, and at the future Electron-Ion ...

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
