Semi-inclusive deep-inelastic scattering off few-nucleon systems: Tagging the EMC effect and hadronization mechanisms with detection of slow recoiling nuclei

Abstract

The semi-inclusive deep-inelastic scattering of electrons off 2 H and 3 He with detection of slow protons and deuterons, respectively, i.e., the processes 2 H(e, e p)X and 3 He(e, e d)X, are calculated within the spectator mechanism, taking into account the final state interaction of the nucleon debris with the detected protons and deuterons. It is shown that by a proper choice of the kinematics the origin of the EMC effect and the details of the interaction between the hadronizing quark and the nuclear medium can be investigated at a level which cannot be reached by inclusive deep-inelastic scattering. A comparison of the results of our calculations, containing no adjustable parameters, with recently available experimental data on the process 2 H(e, e p)X shows a good agreement in the backward hemisphere of the emitted nucleons. Theoretical predictions at energies that will be available at the upgraded Thomas Jefferson National Accelerator Facility are presented, and the possibility to investigate the proposed semi-inclusive processes at electron-ion colliders is briefly discussed.

Neutron Parton Structure And The Light-front Spectral Function Of 3He

“…We are presently planning to test our extraction procedure of neutron asymmetries from 3 He asymmetries using the LF SF and including in our LF description the FSI between the jet produced from the hadronizing quark and the two-nucleon spectator system through an extension to the LF framework of the GEA of Refs. [13,14], as we did in the NR case [5,7].…”
