Systematic Measurements of Identified Particle Spectra in pp, d+Au and Au+Au Collisions from STAR

TL;DR

This paper presents systematic measurements of identified particle spectra in proton-proton, deuteron-gold, and gold-gold collisions at various energies, providing detailed data for understanding particle production in high-energy nuclear collisions.

Contribution

It provides comprehensive spectra data for identified particles across different collision systems and energies, expanding the experimental database for heavy-ion collision studies.

Findings

Particle spectra vary with collision system and energy.

Data supports models of particle production and nuclear matter behavior.

Results aid in understanding quark-gluon plasma formation.

Abstract

Identified charged particle spectra of $\pi^{\pm}$, $K^{\pm}$, $p$ and $\pbar$ at mid-rapidity ($|y|<0.1$) measured by the $\dedx$ method in the STAR-TPC are reported for $pp$ and d+Au collisions at $\snn = 200$ GeV and for Au+Au collisions at 62.4 GeV, 130 GeV, and 200 GeV. ...
