Recent NA49 results on Pb+Pb collisions at CERN SPS

TL;DR

This paper presents recent results from NA49 on Pb+Pb collisions at CERN SPS, focusing on baryon transfer, strange particle production, and light nuclei, providing insights into collision dynamics at various energies.

Contribution

It introduces new measurements of strange meson and baryon production at 40 GeV per nucleon and explores baryon transfer and light nuclei formation in nucleus-nucleus collisions.

Findings

Observation of strange meson and baryon yields at 40 GeV A

Analysis of baryon stopping and transfer mechanisms

First results on light nuclei production at this energy

Abstract

In the spirit of establishing a fair reference for nucleus-nucleus collisions, results on stopping and baryon transfer, correlations of the p+p interaction and their consequences are shown. In the discussion of new results from nucleus-nucleus collisions the emphasis is on strange meson and baryon production at different energies - for the first time at 40 GeV A - with the study of light nuclei.
