Abstract

Studies on `strange' particle production have always occupied a very important space in the domain of Particle Physics. This was and is so, just because of some conjectures about specially abundant or excess production of `strange' particles, at certain stages and under certain conditions arising out of what goes by the name of `Standard' model in Particle Physics. With the help of Hagedornian power laws we have attempted to understand and interpret here the nature of the $p_T$-spectra for the strange particle production in a few high energy nuclear collisions, some interesting ratio-behaviours and the characteristics of the nuclear modification factors that are measured in laboratory experiments. After obtaining and analysing the final results we do not confront any peculiarities or oddities or extraneous excesses in the properties of the relevant observables with no left-over problems or puzzles. The model(s) used by us work(s) quite well for explaining the measured data.

Summary

Introduction

Studying the nature of particle production in protonproton collisions is important and interesting in itself, as it might shed light on the basic mechanism for production of particles. It could serve as a necessary benchmark for the physics developments in ultra-relativistic heavy ion collisions [1,2]. Enhancement of strangeness productions was/is one of the powerful diagnostics for the formation of quark gluon plasma (QGP) in relativistic heavy ion collisions and the colliders (RHIC). We precisely point out the conclusions to be arrived at
