Description

The existence and location of the QCD critical point are objects of both experimental and theoretical studies. The comprehensive data collected by NA61/SHINE at the CERN SPS during a two-dimensional scan in beam momentum (13$\textit{A}$-150$\textit{A}$ GeV/$\textit{c}$) and system size ($\textit{p}$+$\textit{p}$, $\textit{p}$+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb) allows for a systematic search for the critical point of strongly interacting matter through the analysis of the scaled factorial moments of the second and higher orders as a function of the phase space cell size in the transverse momentum plane.

The recent results will be presented for protons and negatively charged hadrons from Pb+Pb collisions at 13$\textit{A}$ ($\sqrt{s_{NN}}\approx$ 5.1 GeV), 30$\textit{A}$ GeV/c ($\sqrt{s_{NN}}\approx$ 7.6 GeV), and Ar+Sc at 13$\textit{A}$, 19$\textit{A}$, 30$\textit{A}$, 40$\textit{A}$, 75$\textit{A}$, and 150$\textit{A}$ GeV/$\textit{c}$ beam momentum ($\sqrt{s_{NN}}\approx$ 5.1-16.8 GeV). No intermittency signal is observed, which seems to be in tension with the corresponding results of the STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC).
