Automating a historic code base for a high precision Bs0 oscillation frequency measurement with LHCb data — Quentin Führing and •Kevin Heinicke — Experimentelle Physik 5, TU Dortmund
The upcoming, third data taking period of the Large Hadron Collider will provide a significantly increased dataset, required to continue the systematic search for physics beyond the Standard Model.
Many measurements using the already existing LHC dataset will be repeated, facing new challenges due to the increased statistics. In this talk, a brief overview of the ongoing, updated measurement of the Bs0-meson oscillation frequency Δ ms using a sample of Bs0→ Ds−π+ decays, recorded by LHCb between 2015 and 2018 at √s = 13TeV is given. The tool stack to automate large parts of the analysis pipeline is presented, combining up-to-date python packages with existing, historically grown C++ code and showcasing possible best practices to speed up upcoming, similar analyses.
