Résumé |
Recent advances on anomaly matching elucidates that the topology of QFT can constrain
the possible phase diagram more strongly than we have thought. We show that QCD with
massless fundamental quarks has not only the perturbative chiral anomaly but also the
anomaly involving two-form gauge fields. As an application, we consider "Z3-QCD", which is
the QCD with the twisted quark boundary condition, and show that some of symmetries
must be broken at any circle radius ("temperatures") and quark chemical potentials. |
