Detailed Description

Representation of particles from a HepMC::GenEvent.

Constructor & Destructor Documentation

Rivet::Particle::Particle ( )

inline

Default constructor.

Deprecated:: A particle without info is useless. This only exists to keep STL containers happy.

bool Rivet::Particle::fromDecay ( ) const

Determine whether the particle is from a hadron or tau decay.

Specifically, walk up the ancestor chain until a status 2 hadron or tau is found, if at all.

Note: This question is valid in MC, but may not be answerable experimentally – use this function with care when replicating experimental analyses!

bool Rivet::Particle::hasAncestor ( PdgId pdg_id ) const

Check whether a given PID is found in the GenParticle's ancestor list

Note: This question is valid in MC, but may not be answerable experimentally – use this function with care when replicating experimental analyses!
