Search for critical behavior of strongly interacting matter in the NA61/SHINE experiment / Prokhorova, Daria (St. Petersburg State U.) /NA61/SHINE
NA61/SHINE is a fixed-target experiment at CERN SPS which studies strongly interacting matter. The search for experimental signatures of the critical point is performed via a comprehensive two-dimensional scan of the phase diagram of strongly interacting matter by changing beam momenta (13A - 150A GeV/c) and the size of colliding systems (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb). [...]

NA61/SHINE experiment at CERN SPS: Recent results, current status and perspectives / Brzychczyk, Janusz (Jagiellonian U.) /NA61/SHINE
The NA61/SHINE experiment at the CERN SPS studies hadron production properties in hadron-nucleus and nucleus-nucleus collisions. Recent results from p+p, Be+Be and Ar+Sc interactions provide new data on the system size and energy dependence of hadron multiplicities, spectra and fluctuations. [...]

Pseudorapidity dependence of multiplicity and transverse momentum fluctuations at the SPS energies / Prokhorova, Daria (St. Petersburg State U.) /NA61/SHINE
A search for the critical behavior of strongly interacting matter was done by studying the event-by-event fluctuations of multiplicity and transverse momentum of charged hadrons produced in inelastic p+p collisions and central Be+Be and Ar+Sc collisions at the NA61/SHINE experiment. Results for energy dependence of the scaled variance of the multiplicity distribution and for two families of strongly intensive measures of multiplicity and transverse momentum fluctuations Δ[PT, N] and Σ[PT, N] were presented.

Recent results of strong interaction program from NA61/SHINE experiment at CERN SPS / Melkumov, Georgy (Dubna, JINR) /NA61/SHINE
The NA61/SHINE experiment at the CERN SPS pursues a rich program of strong interactions. The main physics goals of this program are the study of properties of the onset of deconfinement and search for the signatures of the critical point of strongly interacting matter by performing the two-dimensional scan in a broad region of energy (beam momentum 13A-158A GeV/c) and system size (p+p, Be+Be, Ar+Sc and Xe+La).Recent NA61/SHINE results on particle spectra and event-by-event fluctuations in p+p, Be+Be and Ar+Sc collisions are shown with emphasis on the measurements of particle ratios, namely of pion a strangeness production, multiplicity fluctuations versus energy and the system size of colliding nuclei.It will be shown that the hadron production properties in heavy ion collisions which change rapidly in the low SPS energy domain and are interpreted as the beginning of quark-gluon plasma production – onset of deconfinement could be also the case in inelastic p+p interactions and probably in Be+Be collisions.The paper presents a selection of NA61/SHINE results on particle production properties discussed together with existing data from the NA49 collaboration.

Strong and Electromagnetic Collective Effects from NA61/SHINE / Marcinek, Antoni (Cracow, INP) /NA61/SHINE
This contribution presents new NA61/SHINE results on collective effects, including spectator-induced electromagnetic (EM) phenomena in charged pion emission in collisions at beam momentum of 150A GeV/c as well as directed flow for protons and charged pions as a function of transverse momentum and centrality in Pb+Pb collisions at 30A GeV/c. EM effects bring new, independent information on the space-time properties of the system. [...]

Recent Results from Proton Intermittency Analysis in Nucleus--Nucleus Collisions from NA61 at CERN SPS / Davis, N (Cracow, INP) ; Antoniou, N (Athens U.) ; Diakonos, F K (Athens U.) /NA61/SHINE
The search for experimental signatures of the critical point (CP) of strongly interacting matter is one of the main objectives of the NA61/SHINE experiment at CERN SPS. In the course of the experiment, an energy (beam momentum 13A–150A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan is performed. [...]

Recent results from the strong interaction programme of the NA61/SHINE experiment / Stefanek, Grzegorz (Jan Kochanowski U., Kielce (main)) /NA61/SHINE Collaboration
The exploration of the QCD phase diagram (T-$\mu_{B}$) particularly the search for a phase transition from hadronic to partonic degrees of freedom and the critical point is one of the most challenging theoretical and experimental tasks in present heavy ion physics. Unfortunately the QCD predictions are to a large extent qualitative, as QCD phenomenology at finite temperature and baryon number is one of the least explored domains of the theory. [...]
