124 Chapter 10. Conclusion and Outlook
only be computed in a Glauber framework.
To conclude we would also like to propose some points of interest towards the
future that might contribute to a better understanding of A(e, e ′ p) nuclear reactions,
and, in particular, the transparency phenomenon
• Extension of the eikonal/Glauber method : higher order terms to increase the
accuracy of the transversal momentum distribution, proper inclusion of spinorbit,
spin-spin, non-central corrections to the adopted potentials and scattering
amplitudes, multiple-scattering extension of the optical eikonal method
through the use of realistic nucleon-nucleon interaction potentials
• Effect of short-range correlations at high Q 2 : particularly useful in this context
are the two-nucleon knockout experiments and the corresponding polarization
observables to gain some insight into the role of the strong central and tensor
components of these correlations [124, 125, 126, 127]
• Inclusion of recent experimental results on nucleon form factors : in this work
we have performed all calculations with the standard dipole form for the electromagnetic
form factors. Since the reaction strength is heavily influenced by
the elastic nucleon form factors, one should make use of the available experimental
results and QCD-based predictions for these form factors
• Hybrid models : at high Q 2 the incoming foton is able to probe the quark
degrees of freedom in the struck nucleon, and a correct combination of QCD
modelling and nuclear reaction theory might result in a more accurate description
of the physics governing the A(e, e ′ p) reaction
• Usage of other reaction frames : standard nuclear calculations are performed
within the laboratory or center-of-mass frame. It might be more efficient to
consider another framework, as is done for example in Light Cone theory,
where some of the properties inherent to high-energy reactions are already
incorporated in the formalism
