# Evidence for divergent baryon-number susceptibility in QCD matter - High Energy Physics - Phenomenology

Abstract: The baryon-number density formed in relativistic nuclear collisions, versusthe chemical potential of the freeze-out states, is systematically studied onthe basis of existing measurements. A remarkable power-law behaviour of thebaryon-number susceptibility is found at the SPS, consistent with the existenceof a QCD critical point at $\mu {B,c}\simeq 214$ MeV, $T c\simeq 155$ MeV. Theequation of state in different asymptotic regimes of the critical region isalso examined and confronted with freeze-out states in these experiments.
