How to

For the DecayDescriptor in CombineParticles in DaVinci, you need to know the name of the particles which can be used. This list can be dumped the following way on lxplus:

Dump Text File

SetupLHCb
dump_db_to_files.py -c sqlite_file:$SQLITEDBPATH/DDDB.db/DDDB -s /param/ParticleTable.txt

which will dump the file in the folder 'DDDB/param'. You can change the folder the file is dumped to with the -d option.

Alternatively you can get the table printed with:

SetupDaVinci
dump_particle_properties

and then go to 'Database → Standard →DDDB' and look for 'param/ParticleTable.txt'
