We show that the quark fragmentation function D(z) and the quark distribution function q(x) are connected in the z -> 1 limit by the approximate relation D(z)/z≃q(2-1/z), where both quantities are in their physical regions. Predictions for proton production in inelastic e+e- annihilation, based on the new relation and standard parametrizations of quark distribution functions, are found to be compatible with the data.

Abstract

We show that the quark fragmentation function D(z) and the quark distribution function q(x) are connected in the z -> 1 limit by the approximate relation D(z)/z≃q(2-1/z), where both quantities are in their physical regions. Predictions for proton production in inelastic e+e- annihilation, based on the new relation and standard parametrizations of quark distribution functions, are found to be compatible with the data.
