We wanted to find out more about how the electrons and muons in our events were paired in the different energies. I created histograms for both the 8 TeV and the 13 TeV showing the pairings of electrons and muons.
tW Histograms
The histograms on the left were created using data from the 13 TeV data. The ones on the right were created using 8 TeV data. The top row of histograms are 1D histograms showing the number of events that have a certain number of electrons or muons. Exact numbers and percentages appear on the legends attached to the histograms.
The histograms on the bottom row are 2D histograms showing the number of events with combination of muons and electrons. Again, exact numbers and percentages appear on the legends.
ttBar Histograms
These histograms are the same except they come from ttBar Data.
Additional Information
For each file there was a total of 10000 events the percentage was calculated using this.

Histograms for ttBar and tW
Top ^
We wanted to compare the number of particles that pass cuts at 8 TeV and the number of particles that pass cuts at 13 TeV, so I created 1D and 2D histograms for that purpose.
Note: I could not create 2D histograms for tHq; there are no events in which 2 leptons appear. Shown here.
Electrons
The histogram on the left is a 1D histogram showing the number of events, in both 8 TeV and 13 TeV, that pass the momentum cuts. The cuts appear on the legend attached to the hist.
The histograms on the right are 2D histogram of the momentum of two electrons, one leading and one sub-leading. The top histogram uses particle in the 8 TeV events that pass the cuts and the bottom histogram uses 13 TeV.
Muons
These histograms use the same cuts as the electron histograms.
Additional Information
All of the particles on the histograms have passed the eta cut (2.4 for electrons and 2.1 for muons). The percentages were found by dividing the number of particles that met the cut and the total number of leptons of the status and flavor.

Event Histograms for tHq and ttBar tau
Top ^
These were done the same way as the ttbar and tW event histograms.
The following graphs show the energies of two different flavored leptons. The x-axis is electrons and the y-axis is muons. Both the electrons and the muons were passed through eta cuts. For the muons the eta cut was 2.1 and for electron the eta cut was 2.4. There are 10 GeV intervals between the cuts and the cuts go to a maximum of 60 GeV. the legends to the right of the graphs show a few of the percentages and counts from the data.
Note: I could not create 2D histograms for tHq; there are no events in which 2 leptons appear. Shown here.
All of the particles on the histograms have passed the eta cut (2.4 for electrons and 2.1 for muons). The percentages were found by dividing the number of particles that met the cut and the total number of leptons of the same status and flavor.
These histograms show the difference between the number of particles that pass certain PT cuts in 8 TeV and 13 TeV. Unlike the similar histograms on this page these were created with no Eta cut.
Note: I could not create 2D histograms for tHq; there are no events in which 2 leptons appear. Shown here.
These histograms were created to show the change in accepted particles when the eta cut changes. They use the same PT cuts as Histograms for ttBar and tW and Event Histograms for tHq and ttBar tau. The increments are shown on the graphs in the percentages legend.
Using different files with different numbers of events, I generated a histogram for the Eta and momentum as well as a two-dimensional histogram graphing both Eta and momentum together. I generated theses for Top and Higgs for all three files.
Using different files with different numbers of events, I generated a histogram for the Eta and momentum as well as a two-dimensional histogram graphing both Eta and momentum together. I generated theses for b jets and Ws for all three files.
These histograms were generated from ttbar files. The other recent histograms were created using 13 TeV. I used 13 TeV to generate the first histograms. The second set of histograms show 8 TeV for comparison.
I used the same files for these histograms as I did for Histograms for b jets and W. I only looked for b-jets, but the graphs show only b jets that have certain parents.
Acceptance histograms for muons and electrons from 1000, 750, 500 from tprime
Top ^
These histograms show the number and percentage of muons/electrons that pass PT cuts up to 60 TeV and starting at 10 TeV. The red graph is for muons and the blue graph is for electrons. The legends on the sides show the percentage of particles that pass the given cut. These graphs were made with no eta cuts.
Acceptance histograms for muons and electrons from 1000, 750, 500 with eta cuts from tprime
Top ^
These histograms show the number and percentage of muons/electrons that pass PT cuts up to 60 TeV and starting at 10 TeV. The red graph is for muons and the blue graph is for electrons. The legends on the sides show the percentage of particles that pass the given cut. These graphs were made with |eta| < 2.1 for muons and |eta| < 2.4 for electrons.
Muons are subject to a |eta| < 2.1 cut while electrons and bjets are subject to a |eta| < 2.4 cut.
These histogram was generated using a simulated 13 TeV ttbar file that went into b-jets and leptons.
Single Acceptance for muons, electrons, and b-jets.
On the left are the muon and electron acceptance. On the right is the bjet acceptance.

Di-Acceptance two dimensional histograms for b-jets and leptons with eta cuts from 13 TeV ttbar
For the leptons, muons are subject to a |eta| < 2.1 cut and electrons are subject to a |eta| < 2.4 cut. b-jets are also subject to a eta| < 2.4 cut.
This histogram was generated using a simulated 13 TeV ttbar file that went into b-jets and leptons.
Di-Acceptance two dimensional histograms for b-jets and leptons
These histograms were generated using the same parameters as the ttbar ones above.
For the leptons, muons are subject to a |eta| < 2.1 cut and electrons are subject to a |eta| < 2.4 cut. b-jets are also subject to a eta| < 2.4 cut.
The table shows the percentage of events that meet or pass the given cut. The total number of events is 10000 for both the tprime and the ttbar. The remaining events are not scaled.
