The DecayDescriptor stores information about a decay tree or parts of a decay tree.
Base class for Modules.
Definition: Module.h:72
Calculates 4-momentum of a neutral hadron in a given decay chain e.g.
bool m_allowAnyParticleSource
Whether allow the selected particle to be from any ParticleSource.
void event() override
Action to perform for each event.
std::string m_decayString
Decay string for which one wants to perform the calculation.
int m_iNeutral
Index of the neutral hadron in the decay string.
NeutralHadron4MomentumCalculatorModule()
Constructor: Sets the description, the properties and the parameters of the module.
DecayDescriptor m_decayDescriptor
Decay Descriptor to be initialized with m_decayString.
bool m_allowGamma
Whether allow the selected particle to be gamma.
StoreObjPtr< ParticleList > m_plist
ParticleList that one wants to perform the calculation.
Type-safe access to single objects in the data store.
Definition: StoreObjPtr.h:96
Abstract base class for different kinds of events.
