We first show that the pions produced at high \(p_T\) in heavy-ion collisions over a
wide range of high energies exhibit a scaling behavior when the distributions are
plotted in terms of a scaling variable. We then use the recombination model to calculate
the scaling quark distribution just before hadronization. From the quark distribution
it is then possible to calculate the proton distribution at high \(p_T\), also in the
framework of the recombination model. The resultant \(p/\pi\) ratio exceeds one in the
intermediate \(p_T\) region where data exist, but the scaling result for the proton
distribution is not reliable unless \(p_T\) is high enough to be insensitive to the
scale-breaking mass effects.
