The aim of the NA61/SHINE strong interaction programme is to explore the phase diagram of strongly interacting matter. The main physics goals are the study of the onset of deconfinement and the search for the critical point of strongly interacting matter. These goals are pursued by performing an beam momentum
(13A - 158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan.

Excitation functions for the Gaussian emission source radii difference ($R_{out}^2-R_{side}^2$) obtained from two-pion interferometry measurements in Au+Au ($\sqrt{s_{NN}}=7.7–200$ GeV) and Pb+Pb ($\sqrt{s_{NN}}=2.76$ TeV) collisions are studied for a broad range of collision centralities. The observed nonmonotonic excitation functions validate the finite-size and finite-time scaling patterns...

Fluctuations of and correlations among conserved charges of strong
interactions have long been considered sensitive observables
for the exploration of the structure of the phase diagram of QCD. Cumulants
of conserved charge fluctuations are the most promising experimental observables
in the search for a critical point in the phase diagram of QCD performed in the
beam energy scan...

Considering effective models constructed to be in the same universality class as QCD,
we discuss the role of critical fluctuations in the vicinity of the chiral transition.
In recent lattice calculations [Ejiri et al., Phys. Rev. D 80 (2009) 094505 ] QCD with physical quark
masses is found to be in the scaling regime of the O(4) universality class.
We examine the O(4) scaling...

Recently, STAR beam energy scan (BES) measured the multiplicity distributions of net protons with the maximum transverse momentum extended from 0.8 GeV to 2 GeV. The related higher cumulants (moments) present large deviations from the poisson baselines, showing the potential of discovery the QCD critical point in experiment.
In this talk, we introduce a freeze-out scheme for the...

Modifications in magnitude of fluctuations for different observables
are an excellent probe of a phase transition or its remnant.
In heavy-ion collision, fluctuations related to conserved charges
carried by light and strange quarks play an important role to identify
the QCD chiral crossover and deconfinement properties.
Recent Lattice QCD simulations have revealed that the charmed...
