Abstract

The invariant cross sections for forward charged-hadron production at zero angle in carbon–carbon collisions at a beam kinetic energy of 19.6 GeV per nucleon were measured at the U-70 accelerator in an experiment performed with the aid of a combined spectrometer including beam line 22 and detectors of the modified FODS setup. The beam line rigidity was varied between 7 and 70 GeV/\(c\). The results are compared with the predictions of the FTFP model and a self-similar solution for nucleus–nucleus collisions.

在每个核子束能量为19.6 GeV的情况下，测量碳-碳碰撞中包容性正电荷强子产生的截面

摘要

在U-70加速器上，在包括束线的组合光谱仪的帮助下，在U-70加速器上测量了在碳-碳碰撞中在零角处以每核子19.6 GeV的束动能产生正电荷强子的不变截面22和修改后的FODS设置的检测器。束线刚度在7到70 GeV / （c）之间变化。将结果与FTFP模型的预测以及核-核碰撞的自相似解进行比较。
