During the expansion of a heavy ion collision, the system passes close to the $O(4)$ critical point of QCD, and thus the fluctuations of the order parameter $(\sigma, \vec{\pi})$ are expected to be enhanced.

We also discuss an extended set of transformations, which change the action by a term that is locally known on the level of the quantum effective action.
