bamboo - A high-level HEP analysis library for ROOT::RDataFrame: An analysis example with the CMS NanoAOD format

These proceedings present an overview and features of a bamboo framework designed for HEP data analysis. The bamboo framework defines a domain-specific language, embedded in python, that allows to concisely express the analysis logic in a functional style. The implementation based on ROOT’s RDataFrame and cling C++ JIT compiler approaches the performance of dedicated native code. Bamboo is currently being used for several CMS Run 2 and Run 3 analyses that rely on the NanoAOD data format for which many reusable components are included.
