WebOne of the fascinating features of chiral symmetry is that sometimes it is not a sym-metry of the quantum ﬁeld theory even when it is a symmetry of the Lagrangian.

Anomalies turn out to WebWhen a symmetry is not there anymore, it means we have to find something to characterize the new configuration of the system; this takes the name of "order parameter".
