Abstract: We discuss the equation of state for 2 flavor QCD at non-zero temperature and density. Derivatives of$\ln Z$with respect to quark chemical potential$\mu_q$up to fourth order are calculated, enabling estimates of the pressure, quark number density and associated susceptibilities as functions of$\mu_q$via a Taylor series expansion. It is found that the fluctuations in the quark number density increase in the vicinity of the phase transition temperature and the susceptibilities start to develop a pronounced peak as$\mu_q$is increased. This suggests the presence of a critical endpoint in the$(T, \mu_q)\$ plane. College of Science 408 412
