The incoming lepton.
Definition: DISDiffHadron.hh:46
virtual CmpState compare(const Projection &p) const
Compare with other 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! ...
