Here, I examine the comparison of embedding tracks to data tracks for VPDMB-triggered jets. The matching is to particle-jets and the tracks are simply matched geometrically.

Figure 1

The scatter is qualitatively quite similar between data and embedding.

Figure 2

The match in z appears to be quite reasonable between data and embedding. The "turn-on" appears matched quite nicely, and above the turn-on appears excellent agreement. The match in jT also appears to be quite nice. Statistics die off rather quickly above 1 GeV/c, however, the low jT appears spot-on.

It is also useful to examine the distribution of dE/dx. Below I post the distribution of dE/dx as a function of track momentum. In the overlay plots, the distribution for tracks before the pion cuts are on the left while those after are on the right.

Figure 3

In the scatter plots while the general features appear similar it does appear there are more tracks above the pion band in data than embedding.

Figure 4

A similar situation to Fig. 4 is seen after the pion cuts.

Figure 5

In the overlay plots the comparison is not so bad prior to the pion cuts (left). The comparison on the left-side of the peak shows the embedding a bit high. After the pion cuts, the embedding is a bit high on the right-side of the peak. Above the peak, the embedding statitics drop off. What is there appears to be too low.

Figure 6

Prior to the pion cuts, the momentum distribution appears pretty close until about 10 GeV/c. After the pion cuts, the distribution appears a bit too hard in the embedding. This is possibly also a reflection of the dearth of tracks above the pion band in Fig. 4, most of which seem to occur at low momentum.
