Abstract

The critical point of strongly interacting matter is searched for at the CERN SPS by the NA61/SHINE experiment in central 40Ar + 45Sc collisions at 13A, 19A, 30A, 40A, and 75A 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.
