摘要：

Nonlinear susceptibilities up to the eighth order have been constructed in QCD with two flavors of dynamical quarks. Beyond leading order, they exhibit peaks at the crossover temperature, T-c. By analyzing their behavior in detail, we find that the dominant contributions near T-c come from a set of operators with a remarkably simple topology. Any effective theory of QCD near T-c must be able to explain these regularities.
