The critical point of strongly interacting matter is searched for at the CERN SPS by the NA61/SHINE experiment in central $^{40}$Ar +$^{45}$Sc collisions at 13$A$, 19$A$, 30$A$, 40$A$, and 75$A$ GeV/$c$. The dependence of the second-order scaled factorial moments of proton multiplicity distributions on the number of subdivisions in transverse momentum space is measured. The intermittency analysis uses statistically independent data sets for every subdivision in transverse and cumulative-transverse momentum variables. The results obtained do not indicate the searched intermittent pattern. An upper limit on the fraction of correlated protons and the intermittency index is obtained based on a comparison with the Power-law Model.

  1. Understanding the Intermittency Signal in RHIC-STAR Data through Modeling

    nucl-th 2026-06 unverdicted novelty 4.0

    Hybrid model constrains STAR intermittency data to small, nearly energy-independent critical-like fractions, indicating limited critical-point contribution.

  2. NA61/SHINE results on search for critical point

    nucl-ex 2026-05 unverdicted novelty 2.0

    NA61/SHINE status report finds no indication of the QCD critical point in heavy-ion collisions via net-charge fluctuations, pion femtoscopy, and hadron intermittency, plus new analysis techniques.
