Low energy hadron production at zero angle in proton-nucleus collisions at 70 GeV

The cross sections for production of pions, kaons, protons, antiprotons and deuterons at zero production angle have been measured in proton-nucleus collisions at 70 GeV in the momentum range of secondaries from 1.5 up to 3 GeV/c. Thin Al, Cu and W targets have been used in these measurements. The data onA-dependence of the production cross sections and particle yield ratios in momentum range from 1.35 up to 3.0 GeV/c are presented.
