Modern high-energy physics (HEP) enterprises, such as the Belle II experiment [1,2] at the KEK laboratory in Japan, create huge amounts of data. Sophisticated algorithms for simulation, reconstruction, visualization, and analysis are required to fully exploit the potential of these data.We describe the core components of the Belle II software that provide the foundation for the development of complex algorithms and their efficient application on large data sets.Keywords Belle II · basf2 · framework · event data model · parallel processing · conditions database
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
