You find the full table in http://www.physik.uzh.ch/~nchiapol/lhcb/particles.txt
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
Use CondDBBrowser
Alternatively, you can also use the CondDBBrowser. Type:
CondDBBrowser
and then go to 'Database → Standard →DDDB' and look for 'param/ParticleTable.txt'
The syntax of the DecayDescriptor is described in the DecayFinder (!) class reference of DaVinci. In addition there is a very helpful FAQ
Often you can find the full DecayDescriptor in the corresponding stripping line in SVN
