Detailed Description

Function Documentation

cascadeContains()

bool Rivet::cascadeContains	(	const Particles &	parts,
		const vector< int > &	pids,
		bool	absolute,
		bool	ignorephoton
	)

Check whether a set of particles' decay chains can contain the requested list of pids.

Note

if absolute is true, then only the absolute values of pids are compared.

if ignorephoton is true, then photons are ignored when searching for the set of particles.

containsPID()

bool Rivet::containsPID ( const Particles &  parts, int  id, bool  abs = false  )

inline

Check for pid membership in a list of particles.

Note

if abs is true, then only abs pids are checked.

isRadiative()

bool Rivet::isRadiative ( const Particle &  part )

inline

Check whether a particle is radiative.

Note

A particle is considered radiative if (1) it has only one mother particle and (2) one of its siblings has the same pid as the mother particle.
