Abstract

The main goals of the NA61/SHINE experiment at the CERN SPS are the search for the critical point of strongly interacting matter and the study of the properties of the onset of deconfinement. These aims are pursued by performing a two-dimensional scan of the phase diagram of strongly interacting matter by varying the momentum and size of the colliding nuclei. This contribution summarises the latest results from the NA61/SHINE experiment, in particular, new results on spectra and yields of ϕ meson in p+p interactions at 40, 80 and 158 GeV/c and K+ and K- production in central Be+Be collisions at mid-rapidity. In addition, results on system size dependence of particle yield ratios and fluctuations are presented.

Summary

Introduction

NA61/SHINE [1] is a fixed-target experiment located in the H2 beam line of the CERN SPS accelerator complex. The main detector system is a set of five Time Projection Chambers (TPCs) which allows a precise measurement of the particle momenta and provides particle identification via the measurement of the specific energy loss, dE/dx. The programme is motivated by the discovery of the onset of deconfinement in Pb+Pb collisions at 30A GeV/c by the NA49 experiment [2, 3]. To achieve this goal a two-dimensional scan of the phase diagram of strongly interactiong matter is performed by varying the beam momentum (13A-150/158A GeV/c) and the size of the colliding nuclei (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb)
