TTTT Production Cross-Section Measurement

This project contains the code, documentation, and results of the TTTT production cross-section measurment in the tri-lepton channel.

To run this analysis, first aquire relevant MC files for signal(TTTT), and main backgrounds(TTW, TTZ, TT). These should be in the "Minitree" format. Then checkout the code from Github. After acquiring the code, follow the standard cmake build process of

cd project_directory
mkdir build
cd build
cmake ..
make

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

./main -f path_to_minitree_file

This will create a results ROOT file containing a set of histograms extracted from the Minitree. Create one of these for each input Minitree. The results are then usually processed in Jupyter Notebooks to produce final plots/measurements. For example, a basic listing of generated histograms can be found here

A brief rundown of the general analysis framework, FilVal, can be found here.
