摘要：

We present new measurements of pi-0 production at high transverse momenta (p(T)) for pi- and p interactions on Be and Cu targets at 500 GeV/c. The observed dependence of the yields as a function of p(T) and rapidity (y) is compared with expectations from leading-log QCD over a kinematic range in which the inclusive cross sections fall by more than 4 order of magnitude.
