This repository contains the main software of the Belle II experiment.
It is used in all aspects of the data-processing chain, such as
- unpacking of real raw data,
- generating simulated data,
- reconstruction of particle decays (tracking, clustering, ...)
and high-level "analysis" reconstruction (such as applying selection criteria, vertex fitting, ...).
In addition to the code of this repository, the following three repositories are required:
- Belle II tools (public repository, internal repository): Scripts to install and set up basf2
- Belle II externals (public repository, internal repository): Manages external dependencies of basf2
- Belle II versioning (public repository, internal repository): Manages the different versions of basf2 and related conditions database global tags
Note that the history of the code is split in a part before (public repository, internal repository) and after (public repository, internal repository) July 7, 2021.
Both parts are combined to a complete history with the b2code-history command.
Head to our documentation to learn about
how to use basf2. If you are unsure about which version of the documentation to
read, click on release-xx-xx-xx (recommended). We
recommend you to start with the lessons of the Beginners' tutorials if you are
just starting out.
More information about the core software can be found in the 2018 paper.
