Pion Production in Proton-Beryllium Collisions at 12.4 GeV/c

Abstract

The absolute cross sections for ${\pi }^{+}$- and ${\pi }^{-}$-meson production in proton-beryllium collisions at 12.4 GeV/c are reported. Measurements were made for laboratory production angles between 0 and 12° and pion momenta between 2 and 6 GeV/c. All recent data for pion production in $p-\mathrm{Be}$ collisions are fitted with an empirical relation first suggested by Sanford and Wang.
