Here is a look at the mass shifts as well as the trigger and reconstruction biases for the dijet asymmetry measurements ...

Figure 1: The size of the mass shifts for the combined topology dijet sample. The top two panels show the shifts for the L2 (left) and JP (right) samples individually. The bottom panel shows the combined correction where each trigger contribution is scaled by the appropriate trigger ratios seen in data. The points for the top two panels are plotted at the bin center and the points for the bottom panel are plotted at the average mass in that bin. The closed squares are particle level and the open are parton level. Red is no track loss, blue is 4% track loss, and green is 7% track loss.

Figure 2: The trigger and reconstruction biases at particle level for three polarized PDF sets. The upper left panel compares the detector level (blue circles) and particle level (red squares) asymmetries for the DSSV PDF set. The detector level points are plotted at average mass of that bin plus the mass shift shown in figure 1. The particle level points are plotted at the average particle level mass. The upper right and middle left panels show the same for the DSSV2009a and LSS2010Pos PDF sets, respectively. The middle right panel shows the detector - particle level asymmetry difference for the three PDF sets. The bottom panel is just a blow-up of the middle right plot.
