“…Surprisingly results for Be+Be and p+p reactions are very close, independent of collision energy. Comparing to heavier systems the data suggest a jump between light and heavy systems as in the case of multiplicity fluctuations [7].…”

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.

“…The very existence of such a CEP is a landmark for identifying the universality class of QCD, and due to its importance for model building and phenomenology, a major target of experimental research programs with ultra-relativistic heavy-ion collisions at BNL RHIC (STAR beam energy scan, Stephans 2006) and CERN SPS (NA49 SHINE, Gazdzicki et al 2006), in future at NICA in Dubna (Sissakian et al 2006) and at FAIR in Darmstadt (Friman et al 2011).…”

Aims. We explore the implications of a strong first-order phase transition region in the dense matter equation of state in the interiors of rotating neutron stars, and the resulting creation of two disjoint families of neutron-star configurations (the so-called high-mass twins). Methods. We numerically obtained rotating, axisymmetric, and stationary stellar configurations in the framework of general relativity, and studied their global parameters and stability. Results. The instability induced by the equation of state divides stable neutron star configurations into two disjoint families: neutron stars (second family) and hybrid stars (third family), with an overlapping region in mass, the high-mass twin-star region. These two regions are divided by an instability strip. Its existence has interesting astrophysical consequences for rotating neutron stars. We note that it provides a natural explanation for the rotational frequency cutoff in the observed distribution of neutron star spins, and for the apparent lack of back-bending in pulsar timing. It also straightforwardly enables a substantial energy release in a mini-collapse to another neutron-star configuration (core quake), or to a black hole.

NA61/SHINE is a multipurpose experiment to study hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. The experiment performs unique measurements for physics of strong interactions as well as important reference measurements for neutrino and cosmic-ray physics. The results from the strong interaction programme uncover rapid changes in collision-energy and system-size dependence of basic hadron production properties-the critical structures. They are attributed to the onset of deconfinement, onset of fireball and may indicate the critical point of strongly interacting matter.
