数据是关于包容性生产的。pi../ sup + -/、K/sup + -/、p和p-bar用于.. pi../ sup +/、K/sup +/和入射到100 GeV核靶上的质子。当P/sub t/ = 0.3和0.5 GeV/c时，结果涵盖了30 ≤ P ≤ 88 GeV/c的运动学范围。所观察到的A的不变截面的依赖表现出显着的简单性，这并不自然地遵循目前的粒子生产模型。结果表明，有限碎裂假说可以推广到包括与核的碰撞。
Data are presented on the inclusive production of ..pi../sup + -/, K/sup + -/, p, and p-bar for ..pi../sup +/, K/sup +/, and protons incident on nuclear targets at 100 GeV. The results cover the kinematic range 30< or =P< or =88 GeV/c for P/sub t/ = 0.3 and 0.5 GeV/c. The observed A dependence of the invariant cross sections exhibits remarkable simplicity, which does not naturally follow from current models of particle production. The results show that the hypothesis of limiting fragmentation can be extended to include collisions with nuclei.
