QCD phase diagram in chiral imbalance with self-consistent mean field approximation
QCD phase diagram in chiral imbalance with self-consistent mean field approximation
We employ a new self-consistent mean field approximation of the Nambu-Jona-Lasinio (NJL) model, which introduces a free parameter $\ensuremath{\alpha}$ ($\ensuremath{\alpha}$ reflects the weight of different interaction channels), to study the effects of the chiral chemical potential ${\ensuremath{\mu}}_{5}$ on QCD phase structure, especially the location of the QCD critical endpoint (CEP). …
