Similarities and differences between the inclusive reactions $$K^ - p \to \bar K^0 X_1 $$ and $$\bar vp \to \mu ^ + X_2 $$

Abstract

We study in detail some aspects of “jet universality” in soft and hard processes interpreted by quark-parton diagrams. Using the framework of the Dual Topological Unitarization model for the soft process\(K^ - p \to \bar K^0 X_1 \) we compare hadron longitudinal momentum distributions and multiplicities in the “one-chain” part of this reaction to those in\(\bar vp \to \mu ^ + X_2 \). We observe not only close similarities (e.g. the same π+/π− ratio over the whole Feynman-x region) but also some significant differences in the jet systemsX1,X2, such as a lower cross-section in the central region and a smaller average multiplicity of the jets inX1.
