1 TTTT Production Cross-Section Measurement

2 =========================================

3 

4 This project contains the code, documentation, and results of the TTTT

5 production cross-section measurment in the tri-lepton channel.

6 

7 To run this analysis, first aquire relevant MC files for signal(TTTT), and main

8 backgrounds(TTW, TTZ, TT). These should be in the "Minitree" format. Then

9 checkout the [code](https://github.com/cfangmeier/TTTT) from Github. After

10 acquiring the code, follow the standard cmake build process of

11 

12 ```bash

13 cd project_directory

14 mkdir build

15 cd build

16 cmake ..

17 make

18 ```

19 

20 Once the code has been built, there should be a `main` executable in the build directory. Call it with the syntax

21 

22 ```bash

23 ./main -f path_to_minitree_file

24 ```

25 

26 

27 This will create a results `ROOT` file containing a set of histograms extracted

28 from the Minitree. Create one of these for each input Minitree. The results are

29 then usually processed in Jupyter Notebooks to produce final

30 plots/measurements. For example, a basic listing of generated histograms can be

31 found [here](./TTTT_Analysis.html)

32 

33 A brief rundown of the general analysis framework, FilVal, can be found [here](./md__home_caleb_Sources_TTTT_AboutFilVal.html).
