Bjorken scaling for hadron-nucleus scattering

ORAL

Abstract

Electron scattering to the continuum for several nuclear samples at energy losses less than those for scattering on free nucleons (x$_{Bj} >$1) has been shown to sense high nucleon momenta arising from hard collisions or correlations within nuclei, using ratios of cross sections.\footnote{K. Sh. Egiyan et al., Phys. Rev. C 68, 014313 (2003).} A similar analysis has been carried out for continuum hadron scattering at lower momentum transfers but including a very wide range of nuclei and several reactions, including proton scattering up to 19.2 GeV/c, proton charge exchange, and pion scattering. These data show the same trends as noted with electrons, but heavier nuclei show systematically enhanced contributions from high nucleon momenta. A wide range of data will be compared to the electron results.
