摘要：
In this talk we present a measurement of the ratio of inclusive cross sections sigma-(p (p) over bar -> Z + b jet)/sigma(p (p) over bar -> Z + jet) at root s = 1.96 TeV based on approximatly 180 pb(-1) of data collected with the DO detector. Combining the Z -> e(+) e(-) and Z -> mu(+)mu(-) channels, the ratio was found to be 0.023 +/- 0.004(stat) +/- 0.002(syst).
