A-dependence of hadronization in nuclei
Autor: Lapikás, H. P. Blok L.
Publikováno v: Phys.Rev.C73:038201,2006
The A-dependence of models for the attenuation of hadron production in semi-inclusive deep-inelastic scattering on a nucleus is investigated for realistic matter distributions. It is shown that the dependence for a pure partonic (absorption) mechanis

The nonlocal implementation of the dispersive optical model (DOM) provides all the ingredients for distorted-wave impulse-approximation (DWIA) calculations of the (e,e′p) reaction. It provides both the overlap function, including its normalization,
