Detailed Description

Function Documentation

isDirect()

bool Rivet::isDirect ( const Particle &  p, bool  allow_from_direct_tau = false, bool  allow_from_direct_mu = false  )

inline

Decide if a given particle is direct, via Particle::isDirect()

A "direct" particle is one directly connected to the hard process. It is a preferred alias for "prompt", since it has no confusing implications about distinguishability by timing information.

The boolean arguments allow a decay lepton to be considered direct if its parent was a "real" direct lepton.

isPrompt()

bool Rivet::isPrompt ( const Particle &  p, bool  allow_from_prompt_tau = false, bool  allow_from_prompt_mu = false  )

inline

Decide if a given particle is prompt, via Particle::isPrompt()

The boolean arguments allow a decay lepton to be considered prompt if its parent was a "real" prompt lepton.
