    abstract = "We look for fluctuations expected for the QCD critical point using an intermittency analysis in the transverse momentum phase space of protons produced around midrapidity in the 12.5 % most central C+C, Si+Si and Pb+Pb collisions at the maximum SPS energy of 158A GeV. We find evidence of power-law fluctuations for the Si+Si data. The fitted power-law exponent is consistent with the value expected for critical fluctuations. Power-law fluctuations had previously also been observed in low-mass collisions. © 2015, The Author(s)."
