英文摘要: The effect of chirality imbalance on the QCD phase diagram is studied within the two flavors NambuJona- Lasinio model. We focus especially on the issues related to how the chiral chemical potential (mu(5)) affects the phase diagram, and find the "chiral catalysis" as well as "inverse chiral catalysis" effects, which are analogous to the magnetic catalysis and inverse magnetic catalysis effects. Furthermore, our results are different from the existing chiral model calculations, namely, there is no CEP5 on the T-mu(5) plane, since the whole phase transition is a crossover. In addition, with the introduction of the chiral chemical potential, various QCD susceptibilities and the corresponding critical exponents are also studied.
