Production of strange particles in a multi-pomeron exchange model

Resumo

An extended version of the multi-pomeron exchange model for the description of pp collisions in a wide energy range (from ISR to LHC) is presented by accounting of strange particle yields. This model effectively includes the interaction of quark-gluon strings in the form of fusion. The yields of different types of particles are differentiated using the Schwinger mechanism of string hadronization. The results on the multiplicity of strange particles and their transverse momentum and correlations are presented and compared to the experimental data. The possible effect of higher resonances on the observed characteristics is discussed, along with the applicability of the Schwinger mechanism.
