Description
Integration of an analysis of Higgs boson decaying to a pair of tau leptons into a ROOT-based C++ framework, making use of recent ATLAS Open Data release. The workflow demonstrates how modern analysis strategies can be easily implemented within a modular structure that combines event selection and object reconstruction. Particular emphasis is placed on the use of ROOT for handling large datasets and producing complex histograms. The framework is designed to be accessible to students and researchers, providing an educational platform while remaining scalable for advanced physics studies. Results are illustrated with reconstructed di-tau invariant mass distributions, highlighting the pedagogical value of the ATLAS Open Data resources using ROOT.
