Analyzing Run 1 LHCb Open Data

All of the LHCb Run 1 data is now available on the CERN Open Data Portal for analysis!

Analyzing the Run 1 LHCb Open Data files (DST files) offers increased flexibility in what information one can extract from the data relative to the LHCb Ntupling Service at the cost of a larger time investment to learn LHCb open source software for creating Ntuples from the DSTs. The following guide can be used to understand how these data can be analyzed.

Simplified Workflow to Get Ntuples

DaVinci is the software that allows you to get inside the DST files and get the information that you need. DaVinci uses options files as inputs; these files contains specifications about the information that you need from the DST files.

In the examples provided, you will find options files with different levels of complexity. That should give you an idea on the structure of these options files. You can find a more detailed explanation about options files in the LHCb Starter Kit.
