Abstract / Description:Inclusive differential cross sections dσpA/dxF and dσpA/dp2t
for the production of K0S, Λ, and Λ particles are measured at HERA in proton-induced reactions on C, Al, Ti, and W targets. The incident beam energy is 920 GeV, corresponding to √s = 41.6 GeV in the proton-nucleon system. The ratios of differential cross sections dσpA(K0 S)/dσpA(Λ) and dσpA( ¯ Λ)/dσpA(Λ) are measured to be 6.2 ± 0.5 and 0.66 ± 0.07, respectively, for xF ≈−0.06. No significant dependence upon the target material is observed.
Within errors, the slopes of the transverse momentum distributions dσpA/dp2t also show no significant
dependence upon the target material. The dependence of the extrapolated total cross sections σpA on the atomic mass A of the target material is discussed, and the deduced cross sections per nucleon σpN are compared with results obtained at other energies.
