To turn the PartilceID back into a human readable string you can use the ParticleProperty Service. To do this you need to add the following lines to your code

Include the following headers

#include "Kernel/IParticlePropertySvc.h"
#include "Kernel/ParticleProperty.h"

create a private data member

LHCb::IParticlePropertySvc* m_ppSvc;

initialize the data member in the constructor or the initialize() function

m_ppSvc = svc<LHCb::IParticlePropertySvc>("LHCb::ParticlePropertySvc", true);

afterwards you can use the service to get the ParticleProperties

m_ppSvc->find(particleID)->name();

The ParticlePropertySvc is available in DaVinci as well. The DVAlgrithm comes with an accessor function ppSvc() so the service can be used directly

ppSvc()->find(particleID)->name();
