Non-Gaussian Fluctuations near the QCD Critical Point
Non-Gaussian Fluctuations near the QCD Critical Point
We study the effect of the QCD critical point on non-Gaussian moments (cumulants) of fluctuations of experimental observables in heavy-ion collisions. We find that these moments are very sensitive to the proximity of the critical point, as measured by the magnitude of the correlation length $\ensuremath{\xi}$. For example, the cubic …
