Measurement of Cross Sections for Inclusive Forward Charged Hadron Production in Carbon-Carbon Collisions at Beam Energy of 19.6 GeV per Nucleon

摘要

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.
