摘　　要：A Glauber multiple scattering theory in terms of pations and nucleons is applied to study productions of kaon, lambda and antilambda ill 50 GeV proton-nucleus scatterings at JHF (the Japan Hadron Facility). Tile ratios of tile differential cross sections of nucleontungsten to nucleon-beryllium are calclutated versus the transverse momentum at central rapidity. The cancellation between the single and double scattering amplitudes leads to nuclear enhancement of strangeness production at central rapidity.A Glauber multiple scattering theory in terms of pations and nucleons is applied to study productions of kaon, lambda and antilambda ill 50 GeV proton-nucleus scatterings at JHF (the Japan Hadron Facility).
