Finite-size scaling as a tool in the search for the QCD critical point in heavy ion data
ES Fraga, LF Palhares, P Sorensen - Physical Review C—Nuclear Physics, 2011 - APS
Given the short lifetime and small volume of the quark-gluon plasma (QGP) formed in heavy
ion collisions, a possible critical endpoint (CEP) will be blurred in a region and the effects …
