Run-11 Transverse Jets: Update to Jet Group (April 8, 2014)

After the jet call, I promised to post data-embedding comparison plots with binning that more sensibly comports with the edges of the pT cut-offs for the various triggers. Here, I post comparison plots for the trigger break-down where the bin-widths match those I use for the asymmetry measurement. This is the same as appears in slide 4 of the presentation.

Figure 1

The VPDMB comparison is the same, perfectly reasonable comparison to which we are well-accustomed.

Figure 2

Here, the JP0 plot is somewhat troubling at the trigger turn-on. It actually appears that there is no turn-on in the simulation. I post, below, a break-down according to software/geometric-trigger classes.

Figure 3

The comparisons for JP1 do not show the discrepancy at low-pT. The trigger turn-on is matched quite well.

Figure 4

The trigger turn-on for JP2 is not quite as well-matched as that of JP1, but it is still quite reasonable. Some of this may be due to the lack of an L2JetHigh evaluation on my end. The disagreement between data and simulation appears not to reach a factor of 2 until around 60 GeV/c.

Figure 5

The AJP comparison is not quite as good as that of JP2. At lower pT, however, the agreement is not bad. The data are actually softer than the simulation in this case. The disagreement is within a factor of 2 below about 50 GeV/c.

Figure 6

In looking at the breakdown into subgroups, it appears the low-pT discrepancy in JP0 is entirely in the software+geometric-JP0 events. The software-JP1/JP2/AJP events all seem to show reasonable agreement between data and simulation.
