FinalState(const Cut &c=Cuts::open())
Construction using Cuts object.
void project(const Event &e)
Apply the projection on the supplied event.
void requirePromptness(bool acc=true, bool allow_from_direct_tau=false, bool allow_from_direct_mu=false)
Require accepted particles to be prompt.
Definition: InvisibleFinalState.hh:38
CmpState compare(const Projection &p) const
Compare projections.
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
const PROJ & declare(const PROJ &proj, const std::string &name)
Register a contained projection (user-facing version)
Definition: ProjectionApplier.hh:170
InvisibleFinalState(bool requirepromptness=false, bool allow_from_direct_tau=false, bool allow_from_direct_mu=false)
Constructor with specific FinalState.
Definition: InvisibleFinalState.hh:23
DEFAULT_RIVET_PROJ_CLONE(InvisibleFinalState)
Clone on the heap.
Base class for all Rivet projections.
Definition: Projection.hh:29
Final state modifier excluding particles which are experimentally visible.
