Semi-inclusive deep inelastic lepton scattering off complex nuclei

TL;DR

This paper explores how semi-inclusive deep inelastic scattering experiments involving complex nuclei can shed light on longstanding issues like final state interactions, the spectator mechanism, medium modifications of nucleons, and the EMC effect.

Contribution

It proposes a method to use coincidence detection in semi-inclusive DIS to investigate fundamental nuclear physics problems.

Findings

Potential to clarify the role of final state interactions

Insights into the validity of the spectator mechanism

Understanding of medium-induced modifications of nucleon structure

Abstract

It is shown that in semi-inclusive deep inelastic scattering (DIS) of electrons off a complex nucleus A, the detection, in coincidence with the scattered electron, of a nucleus (A-1) in the ground state, as well as of a nucleon and a nucleus (A-2), also in the ground state, may provide unique information on several long standing problems, such as : i) the nature and the relevance of the final state interaction in DIS; ii) validity of the spectator mechanism in DIS; iii) the medium induced modifications of the nucleon structure function; iv) the origin of the EMC effect.
