WebJul 27, 2024 · We study the ground states of low-density hadronic matter and high-density color-flavor locked color superconducting phase in three-flavor QCD at finite baryon chemical potential under rotation. We find that, in both cases under sufficiently fast rotation, the combination of the rotation-induced topological term for the η′ meson and the QCD … 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. In particular, Noether’s theorem can be modified in a theory with an infinite number of degrees of freedom; the modification is called “an anomaly”. Anomalies turn out to
