Consideration of various time scales in A-A collisions suggests that it is relevant to determine qq- pair production rate at finite temperature. We have evaluated this rate using standard techniques of finite temperature field theory. At high temperature the rate is proportional to T2 and has a value higher than the rate at T=0. It is also observed that the rate of pair production decreases as one moves away from the Lorentz contracted nuclei, towards the center in the c.m. coordinate system.
