The basic concept of the ReactionFilter Plugin is to use a defined physics reaction, usually described in a configuration file, to analyze the reconstructed data (REST files) event by event testing the hypothesis of the proposed reaction. It creates an output root file referred to as Physics Analysis Root Tree (PART) which in turn will be analyzed by other code like the DSelector.

The plugin applies basic PID selection criteria (time, mass, and dEdx) and by default a Kinematic Fitter to the reconstructed charged track and/or neutral showers in each each event and applies the Kinematic Fitter based on the chosen reaction requirements.


The ReactionFilter plugin is located in ReactionFilter plugin on github and depends heavily on the Analysis Library all part of the halld_recon package.
