Numerical study of the equation of state for two flavor QCD at finite density

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.
