Resources connected to Parity Violation Searches

The paper arXiv:2008.05206 defines some variables X1,...,X3 which spot parity in 2-to-2 (plus X) collision events, and defines other variables V1,...,V19 which do the same for 2-to-3 (plus X) collision events. A further V20,...,V28 extend the latter to non-collision events. (No extension is needed for X1,...,X3.) Although the arXiv submission includes a reference implementation for all these variables in the `ancillary files' section connected to the paper. Related files can also be found in this git repository which may contain further enhancements or upstream changes. In particular, this notebook may come in handy for viewing certain special chiral events.
