Abstrakt: | One of the main physics goals of the NA61/SHINE programme on strong interactions is the study
of the properties of the onset of deconfinement. This goal is pursued by performing an energy
(beam momentum 13A– 158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan.
This paper reviews results and plans of NA61/SHINE. In particular, recently obtained inclusive
spectra in inelastic p+p and centrality selected Be+Be, Ar+Sc interactions at the SPS energies
will be shown. The energy dependence of quantities inspired by the Statistical Model of the Early
Stage (kink, horn and step) shows interesting behavior in p+p interactions, which is not described
by Monte-Carlo models. Moreover a comparison with Be+Be collisions and results from other
heavy ion experiments will be performed. |
