Challenges of Nuclear Shadowing in DIS
arXiv:hep-ph/9807211 · doi:10.1016/S0370-2693(98)01072-7
Abstract
Nuclear shadowing in DIS at moderately small is suppressed by the nuclear formfactor and depends on the effective mass of a hadronic fluctuation of the virtual photon. We propose a solution to the problems (i) of how to combine a definite transverse size of the fluctuation with a definite effective mass, and (ii) of how to include the nuclear formfactor in the higher multiple scattering terms. Comparison of the numerical results with known approximations shows a substantial difference.
