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

open access: yesPhysics 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

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

open access: yes, 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 ...

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

open access: yesEPJ 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 ...

Test of the TMD gluon density in a proton with the longitudinal structure function FL(x,Q2)

open access: yesPhysics Letters B, 2023
We investigate the dependence of the deep inelastic proton structure function FL(x,Q2) on different forms of the transverse momentum dependent (TMD, or unintegrated) gluon distribution.

Neutron Structure Function and A=3 Mirror Nuclei [PDF]

open access: yes, 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 ...

Azimuthal correlations in photoproduction and deep inelastic ep scattering at HERA

open access: yesJournal of High Energy Physics, 2021
Collective behaviour of final-state hadrons, and multiparton interactions are studied in high-multiplicity ep scattering at a centre-of-mass energy s $$ \sqrt{s} $$ = 318 GeV with the ZEUS detector at HERA.

Studies of Nucleon Spin Structure at HERMES [PDF]

open access: yes, 2000
The HERMES experiment studies the spin structure of the nucleon using polarized semi-inclusive deep-inelastic positron scattering and polarized quasi-real photoproduction.

Pole Term and Gauge Invariance in Deep Inelastic Scattering [PDF]

open access: yes, 1998
In this paper we reconcile two contradictory statements about deep inelastic scattering (DIS) in manifestly covariant theories: (i) the scattering must be gauge invariant, even in the deep inelastic limit, and (ii) the pole term (which is not gauge ...

Charged hadron lepto-production off unpolarized protons and deuterons at HERMES

open access: yesEPJ Web of Conferences, 2014
The HERMES collaboration has measured charge-separated pion and kaon multiplicities in semi-inclusive deep-inelastic scattering using a 27.6 GeV electron or positron beam scattering off a hydrogen or deuterium target.

Measurement of Gamma-Ray from Inelastic Neutron Scattering on 56Fe [PDF]

open access: yesEPJ Web of Conferences, 2020
In nuclear reactors, inelastic neutron scattering is a significant energy-loss mechanism which has deep impacts on designments of nuclear reactor and radiation shielding. Iron is an important material in reactor.
