Description
The fixed-target NA61/SHINE experiment at CERN SPS is conducting a rich program on strong interactions,
which covers the study of the onset of deconfinement and the search for the QCD critical point.
To achieve these goals in NA61/SHINE the scan of a broad region of the QCD phase diagram ($T - \mu_B$) by varying the momentum
and the size of colliding systems (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb) have been performed.
New NA61/SHINE results on particle spectra and fluctuations in p+p, Be+Be and Ar+Sc
collisions will be discussed.
Special emphasis will be put on measurements of particle ratios and multiplicity fluctuations versus energy and the system size.
The abtained results reflect very interesting features and might be related to the onset of deconfinement as well as to the onset
of formation of large clusters of strongly interacting matter.
Recently, the experimental setup of NA61/SHINE experiment was supplemented
with Vertex Detector (VD) which was motivated by the importance and the possibility of the first
direct measurements of open charm mesons in heavy ion collisions at SPS energies.
The presentation will also focus on the physics motivation behind the open charm measurements at the SPS energies and will provide
information on future plans of charm flavor measurements in NA61/SHINE experiment.
