TL;DR

This paper reports on the energy dependence of hadron spectra and yields in p+p and Be+Be collisions from the NA61/SHINE experiment, contributing to understanding the onset of deconfinement and the QCD phase diagram.

Contribution

It presents new measurements of hadron spectra and yields in p+p and Be+Be collisions across various energies, advancing the study of the QCD phase transition.

Findings

Energy dependence of hadron yields observed

Preliminary results indicate features related to deconfinement

System-size effects on hadron production analyzed

Abstract

The NA61/SHINE programme on strong interactions covers the study of the onset of deconfinement and aims to discover the critical point of strongly interacting matter by performing an energy and system-size scan over the full CERN SPS momentum range. So far the scans of p+p, $^7$Be+$^9$Be, as well as Ar+Sc have been completed. Results from p+p and Be+Be collisions are now emerging, in particular the energy dependence of hadron spectra and yields. Status and preliminary results from this effort will be presented.
