Purpose

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.

Plugin

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

While the analyzers will usually not need to run this plugin by themselves, since this is generally done by the responsible operator running an analysis launch with all requested reactions from all analyzers at once, it is useful for any analyzer to understand the concept of the ReactionFilter plugin and its functionality, also in view of the fact that the analyzer is responsible to provide the definition of the reaction to the operator of the analysis launch.
