Representation of a HepMC event, and enabler of Projection caching.
Definition Event.hh:22
Project out all final-state particles in an event. Probably the most important projection in Rivet!
Definition FinalState.hh:12
Particle representation, either from a HepMC::GenEvent or reconstructed.
Definition Particle.hh:53
PdgId abspid() const
Absolute value of the PDG ID code.

Particles stableDescendants(const Cut &c=Cuts::OPEN) const
Specialised vector of Particle objects.
Definition Particle.hh:25
const PROJ & declare(const PROJ &proj, const std::string &name)
Register a contained projection (user-facing version)
Definition ProjectionApplier.hh:170
Base class for all Rivet projections.
Definition Projection.hh:29
void setName(const std::string &name)
Used by derived classes to set their name.
Definition Projection.hh:142
Convenience finder of unstable taus.

Definition TauFinder.hh:33
virtual CmpState compare(const Projection &p) const
Compare with other projections.
void project(const Event &e)
Apply the projection on the supplied event.
DEFAULT_RIVET_PROJ_CLONE(TauFinder)
Clone on the heap.
Project out all physical-but-decayed particles in an event.
Definition UnstableParticles.hh:25
