Quark fragmentation function in inclusive hadron scattering: Universality

We extract from 16-GeV/c and 32-GeV/c data on $K^{+}p\to K^{0}X$ and $K^{-}p\to {\overline{K}}^{0}X$ the strange-quark fragmentation function $D_s^{\overline{\mathrm{k}}0}\mathrm{}\left(x\right)\mathrm{}$. We show that it has the right properties expected for such a function. This is in agreement with predictions on the universality of quark fragmentation functions obtained in two-dimensional gauge models, and also with what is suggested in some dual models.
