DecayLanguage data folder contents

You can import decaylanguage.data, then use decaylanguage.data.joinpath(<A_FILE>).open() to access data reliably regardless of how you have installed or are running the package (even from a zip file!).

`DECAY_LHCB.DEC`

Copy of the LHCb experiment main decay file for EvtGen, which describes all generic particle decays.

`decfile.lark`

Lark parser grammar definition file for parsing .dec decay files.

`MintDalitzSpecialParticles.fwf`

An extended PDG data file, prepared by this package's maintainers, for the definitions of special particles used by the Mint program. It is similar to the extended PDG data file mass_width_2008.fwf, see https://github.com/scikit-hep/particle/blob/main/particle/data/README.rst.

`MintDalitzSpecialParticlesLatex.csv`

A list of PDG IDs and LaTeX names for the special Mint program particles defined in the file above.

`MintDalitzSpecialParticles.csv`

The combined data file of special particles used by the Mint program, in a format that is easy for the Particle class to read and easy for physicists to extend or edit.

To regenerate the file from the fixed width file MintDalitzSpecialParticles.fwf run

$ python -m particle.particle.convert extended \
    decaylanguage/data/MintDalitzSpecialParticles.fwf \
    decaylanguage/data/MintDalitzSpecialParticlesLatex.csv \
