| ABSTRACT: |
It is very important to study the QCD phase structure at high temperature and density by numerical simulations of lattice QCD, related to heavy-ion collision experiments. The lattice QCD with finite baryon density is known to have a serious problem called ``sign problem", however notable progress has been gradually achieved in the numerical study at relatively low density by improvements of computation technology in the last several years. Moreover the study of the endpoint of first order phase transition line in the temperature and chemical potential plane, whose existence is suggested by phenomenological studies, is particularly interesting both from the experimental and theoretical points of view. To find this endpoint, event by event fluctuations are measured in heavy ion collisions. In this talk, I will review the recent studies of the QCD phase structure by numerical simulations in the low density region. |
