Strange particle production in $p+p$ collisions at $\sqrt{s}$= 200 GeV

TL;DR

This paper reports measurements of strange particle production in proton-proton collisions at 200 GeV, analyzing transverse momentum spectra, yields, and their dependence on event multiplicity, supporting a mini-jet dominated production mechanism.

Contribution

It provides new experimental data on strange particle spectra at 200 GeV and compares these results with p+bar{p} data and pQCD predictions, highlighting the role of mini-jets.

Findings

<pT> increases with event multiplicity

Data is consistent with mini-jet dominated production

Results agree with pQCD predictions

Abstract

We present measurements of the transverse momentum spectra, yield and <pT> systematics for K0short, Lambda and Anti-Lambda in $p+p$ collisions at sqrt{s}=200 GeV. We show a dependence of the <pT> with event multiplicity and infer that this is consistent with a mini-jet dominated particle production mechanism. These observations are compared to available data from p+bar{p} experiments as well as to pQCD theoretical predictions.
