Final-state effects on superfluidHe4in the deep inelastic regime

Final-state effects on superfluid 4He in the deep inelastic regime.

A study of final-state effects ~FSE! on the dynamic structure function of superfluid He in the GerschRodriguez formalism is presented. The main ingredients needed in the calculation are the momentum distribution and the semidiagonal two-body density matrix. The influence of these ground-state quantities on the FSE is analyzed. A variational form of r2 is used, even though simpler forms turn out...

A study of Final State Effects (FSE) on the dynamic structure function of superfluid 4 He in the Gersch–Rodriguez formalism is presented. The main ingredients needed in the calculation are the momentum distribution and the semidiagonal two–body density matrix. The influence of these ground state quantities on the FSE is analyzed.

Revealing the black-body regime of small-x deep-inelastic scattering through final-state signals.

We derive the major characteristics of inclusive and diffractive final states in deep-inelastic scattering off heavy nuclei for the high-energy (small-x) kinematics in which the limit of complete absorption is reached for the dominant hadronic fluctuations in the virtual photon (the black-body limit of the process). Both the longitudinal and transverse distributions of the leading hadrons are f...

The final state hadrons in polarised deep inelastic scattering

General arguments suggest that the non-perturbative background field in QCD may have a non-trivial spin structure. We discuss how this effect may be manifest in semi-inclusive measurements of fast pions in polarised deep inelastic scattering.
