Open Questions

Does an experimentally accessible QCD critical point exist?
If it exists, where is it located in the QCD phase diagram?
What would constitute convincing experimental evidence?
Can present fluctuation structures be explained by noncritical physics?
Which observables provide genuinely independent information?
Can critical correlations survive the dynamical evolution of a heavy-ion collision?
Can several independent observables identify the same underlying critical behavior?
Which future measurements would most decisively confirm or exclude criticality?
