Highlights from the NA61/SHINE strong-interactions programme

TL;DR

NA61/SHINE at CERN investigates hadron production and fluctuation phenomena across various collision systems to identify the critical point of strongly interacting matter and understand deconfinement onset.

Contribution

This paper summarizes recent experimental results from NA61/SHINE on hadron spectra, fluctuations, and electromagnetic effects in multiple collision systems.

Findings

Observation of hadron spectra across different reactions

Measurement of multiplicity fluctuations and higher-order moments

Detection of electromagnetic effects in spectator regions

Abstract

NA61/SHINE is a multipurpose fixed-target facility at the CERN SPS. The main goals of the NA61/SHINE strong-interactions programme are to discover the critical point of strongly interacting matter as well as to study the properties of the onset of deconfinement. In order to reach these goals, a study of hadron production properties is performed in nucleus-nucleus, proton-proton and proton-nucleus interactions as a function of collision energy and size of the colliding nuclei. In this contribution, the NA61/SHINE results from a strong interaction measurement programme are presented. In particular, the latest results from different reactions p+p, Be+Be, Ar+Sc, and Pb+Pb on hadron spectra, as well as intermittency, higher-order moments of multiplicity fluctuations and spectator induced electromagnetic effects are discussed.
