摘要

我们已经研究了用xF - f - o产生的粲粒子。用350 GeV质子和278 GeV π−s在铁上的质子，通过研究在pμ > 20 GeV/c条件下单介子的产生。给出了魅力生产截面和xF分布。通过将这些结果与不同核目标上的其他测量结果进行比较，可以推断出原子量与强子粲子产生的依赖关系。

Cross sections, xF dependence and A‐dependence in hadronic charm production

We have investigated the production of charmed particles with xF≳.2 with 350 GeV protons and 278 GeV π−’s on iron by studying prompt single muon production for pμ≳20 GeV/c. Charm production cross sections and xF distributions are presented. By comparing these results with other measurements on different nuclear targets, it is possible to infer the atomic weight A dependence of hadronic charm production.
