含π±、K±和 $$(p,\bar p)$$ 在强子衰变的微分截面的Z已被测量为函数的z =Phadron/Pbeam,标度的动量。这些结果是基于1992年期间LEP的ALEPH探测器测量的大约520 000个事件。带电粒子通过ALEPH时间投影室中的电离能损失率来识别。确定了ln(1/z)分布中峰的位置,并将峰位置随质心能量的演化与QCD的预测进行了比较。
AbstractInclusive π±, K± and $$(p,\bar p)$$ differential cross-sections in hadronic decays of the Z have been measured as a function ofz=Phadron/Pbeam, the scaled momentum. The results are based on approximately 520 000 events measured by the ALEPH detector at LEP during 1992. Charged particles are identified by their rate of ionization energy loss in the ALEPH Time Projection Chamber. The position, ξ*, of the peak in the ln(1/z) distribution is determined, and the evolution of the peak position with centre-of-mass energy is compared with the prediction of QCD.
