Description
The measured cross sections for Ks0 and Λ0 (Σ0) production in anti pA reactions at 607 MeV/c incident momentum and the number of quark recombinations give the cross section σ(santi s) for strange particle production for target nuclei with A = 2, 4, 20 nucleons, respectively. The result favours the relation σ(santi s) ∝ A1/3. Scattering of an antiquark off a virtual santi s-pair, or gluon Bremsstrahlung emitted by scattering of an incident antiquark passing through nuclear matter, are possible processes consistent with this relation. Models inconsistent with this relation may be wrong. (orig.)
