The reconstructed mass of the events containing identified b-quarks

Here is the reconstructed mass distribution for the b-tagged W + -jet events (solid histogram). The background shape is shown as a dotted line and has been constrained to the calculated value, events. The sum of background plus Monte Carlo for GeV/ is shown as the dashed line. The inset shows the likelihood fit used to determine the top mass.
