Detailed Description

This module contains names for the various PDG particle ID codes.
The names are the same as in EventKernel/PdtPdg.h.

This module also contains a dictionary pdgid_names mapping ID codes
back to printable strings, and a function pdgid_to_name to do this
conversion.  Similarly, root_names and pdgid_to_root_name translate to
strings with root markup.

pdgid_to_name()

(

id

Convert a PDG ID to a printable string.

pdgid_to_root_name()

python.PDG.pdgid_to_root_name

Convert a PDG ID to a string with root markup.

#
# Table of PDG IDs, associating the ID codes with up to several names.
# This is formatted as one big string to make it easier to maintain
# (don't need to quote everything individually).
# The format of each line is like this:
#
#    mname = id     pname   rname
#
# An attribute mname will be added to this module with a value of id.
# These names are intended to match those in PdgPdt.h.
# pname is a printable name for the entry, and rname is a name
# with root-style markup.  These names will be put into the pdgid_names
# and root_names dictionaries, respectively.  They can be left as `!'
# if no name is available.  pname and rname should not contain spaces.
# Blank lines or those starting with `#' will be ignored.
