# New results on spectra and fluctuations from NA61/SHINE

## TL;DR

The NA61/SHINE experiment investigates the phase diagram of strongly interacting matter by analyzing particle spectra, fluctuations, and correlations across various collision systems and energies to search for the critical point and deconfinement onset.

## Contribution

This paper presents new experimental results on particle spectra, fluctuations, and correlations from NA61/SHINE across multiple collision systems and energies, including first measurements of open charm production.

## Key findings

- Charged kaons spectra analyzed
- Charged pions ratios studied (electromagnetic effects)
- Proton intermittency and anisotropic flow results

## Abstract

The NA61/SHINE experiment aims to discover the critical point of strongly interacting matter and study the properties of the onset of deconfinement. For this purpose we perform a two-dimensional scan of the ($T-\mu_{B}$) phase diagram by varying the energy ($5.1 < \sqrt{s_{NN}} < 16.8/17.3$ GeV) and the system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb) of the collisions. In this article the NA61/SHINE results on particle spectra as well as fluctuations and correlations in p+p, Be+Be, Ar+Sc, and Pb+Pb collisions are presented. In particular, the latest results on charged kaons spectra, charged pions ratios (electromagnetic effects), proton intermittency, and anisotropic flow are discussed. Finally, the motivation, NA61/SHINE plans, and the first measurements of open charm production in heavy ion collisions at the Super Proton Synchrotron energies are shown.
