Contribution

It introduces a comprehensive model that accounts for multiplicity, transverse momentum, and particle correlations, including resonance effects, aligning well with experimental data.

Findings

Model accurately reproduces pion, kaon, and proton yields.

Successfully describes strange and multi-strange hadron correlations.

Extends applicability from ISR to LHC energies.

Abstract

We propose a further development of a multi-pomeron exchange model of pp and p$\bar p$ collisions at high energy. The model describes consistently multiplicity, transverse momentum of charged particles and their correlation in wide energy range (from ISR to LHC) by introducing string collectivity effects in pp collisions. The particles species differentiation is implemented according to Schwinger mechanism. Due to the influence of higher resonances on the yields of observed particles, we implement the production of a large set of hadron resonances with cascade decays. We present the results on pion, kaon and proton yields as a function of the collision energy and the correlation of strange and multi-strange hadrons with multiplicity and compare the results with experimental data.
