Run 9 200GeV New Endcap Gain Data / Simulation Comparison: 200 Run Sample

Here I do data simulation comparisons for the 200 run simulation sample. I also divide jets into barrel and endcap dominant samples ...

 

The comparisons below are made using 200 RFF embedding simulation runs and 86 data runs. The simulation sample starts with run 10136017 and the data sample starts with run 10143045, there are roughly 95 simulation runs between the start of the simu sample and the start of the data sample.

 

The data / simulation comparisons shown below use the correct endcap gains and the correct method of calculating the detector eta of the jet as described in my last blog. The difference between this sample and that used in my previous post (besides the extra runs) is that Pibero has removed the Chi2 < 4 cut from the jet finder. In his studies, he found that the Chi2 distributions did not agree between data and simulation.

 

In addition to the quantities I compared in my last post, I have added comparisons of track and tower (within a jet)  pt, eta, and phi. I have also split my sample into barrel dominated jets (det Eta < 1.0) and endcap dominated jets (det Eta >= 1.0).

 

Figure 1: This figure shows the jet pt spectra for data (Blue) and simulation (Red). The three columns show three different triggers, from left to right: L2JetHigh, JP1, and Untriggered. The top pannel shows the pt for jets with detector eta < 1.0 and the bottom pannel shows the pt for jets with detector eta >= 1.0. The figure for the full detector eta range can be seen here.

 

Figure 2: This figure shows the jet eta spectra for data (Blue) and simulation (Red). The three columns show three different triggers, from left to right: L2JetHigh, JP1, and Untriggered. The top pannel shows the eta for all jets, the middle pannel shows the eta for jets with detector eta < 1.0 and the bottom pannel shows the eta for jets with detector eta >= 1.0.

 

 Figure 3: This figure compares average values of jet pt (top), jet sum track pt (middle), and jet sum tower pt (bottom) for data (blue) and simulation (red). The three columns are again the three trigger conditions and for each pannel, the top row is for the high pt jet and the bottom row is for the low pt jet.

 

 

I have also included a pdf which contains all the quantities I have made comparisons for. Each quantity is seperated into high and low pt jets and all, barrel, and endcap centric jets for a total of 6 plots per quantity. For convienence I will list where plots fall in the pdf:

 

As mentioned above, each quantity has 6 figures associated with it, for each quantity the first page shows the high pt jet for all detector eta, the second page shows the high pt jet for barrel jets (detEta<1), the third page shows the high pt jet for endcap jets (detEta>=1), the third fourth and fifth pages mirror the above but for the low pt jet.
