Is a "New Scaling Hypothesis in High Energy Collisions" Needed?

Abstract
The experimental results used by Dao et al. to support a "scaling-in-the-mean" hypothesis for semi-inclusive processes can also be reproduced by a simple Ansatz for the invariant cross section obeying Feynman scaling, Koba-Nielsen-Olesen multiplicity scaling, and factorization in longitudinal and transverse momenta.
