Description
The NA61/SHINE experiment is a fixed-target, broad acceptance facility at the CERN SPS. This contribution summarizes the most recent results from the strong interactions (SI) NA61/SHINE programme and presents news on the detector upgrade in preparation for the future data taking.
The strong interactions programme consists in a two-dimensional scan in
beam momentum (from 13$A$ to 150$A$/158$A$ GeV/$c$, $\sqrt{s_{NN}}$ from 5.1 to 17.3 GeV) and system size ($p$+$p$, Be+Be, Ar+Sc, Xe+La reactions). The experiment searches for the second-order critical end-point in the temperature versus baryo-chemical potential phase diagram and studies the properties of the onset of deconfinement discovered by its predecessor, NA49 at the CERN SPS.
The presented new results include $K/\pi$ multiplicity ratios as a function of energy as well as identified hadron spectra in Be+Be and Ar+Sc collisions, singly and multi-strange hadron production in $p$+$p$ reactions, multiplicity and net-charge fluctuations measured by higher order moments in $p$+$p$, Be+Be and Ar+Sc collisions, proton and charged hadron intermittency in Ar+Sc and Pb+Pb reactions, two-particle correlations in Be+Be, HBT measurements in Ar+Sc and collective electromagnetic effects in Ar+Sc collisions.
