    "abstract": "Quark-quark double scattering in eA DIS and its contribution to quark and\nanti-quark fragmentation functions are investigated with the generalized\nfactorization of the relevant twist-four processes in pQCD. It is shown that\nthe resulting modifications to quark and anti-quark fragmentation functions are\ndifferent. While the numerical size of these effects cannot be determined from\npQCD, the structure of our result leads to a number of qualitative predictions\nfor the relative size of the effect for different hadrons. These qualitative\npredictions agree with the multiplicity ratios for positive and negative\nhadrons as observed by HERMES.",
