It provides a comprehensive comparison of kaon and phi production data, demonstrating a unified participant scaling behavior across various experiments and collision energies.

Findings

Kaon and phi yields scale smoothly with participant density.

Participant density dependence observed in proton-nucleus collisions.

Consistent trends across AGS and SPS energy ranges.

Abstract

Data on kaon and $\Phi$ production in nuclear collisions as a function of centrality are analysed both at AGS and SPS energy range. We compare the results of several experiments, looking for common trend in `participant scaling' of production yields. We find a smooth description of scaled kaon and $\Phi$ yields as a function of participant density. We also show a participant density dependence of kaons and $\Phi$ produced in the forward hemisphere for proton-nucleus collisions.
