ROOT analysis of Monte Carlo particle physics simulations with ATLAS OpenData

This laboratory project involved analysing data from particle physics simulations and real collision data from ATLAS at CERN. The simulations were based on Monte Carlo algorithms using the expectation values from particle physics equations. The analysis involved computing the cross-sections of different particle decays, making selection cuts to remove background data, and using different fitting methods to make estimates of the remaining background data. This project was completed using C++ and ROOT, a data analysis package from CERN, to analyse and visualise the data respectively

See the project here and our final report here.

Histograms featuring simulation data (red) and real data (blue) for the gg → H → 4 lepton decay channel and the Z-boson → electron decay respectively. The difference between red and blue histograms is a result of irremovable background events (generally due to strong interactions)
