Detailed Description

FS modifier to exclude classes of particles from the final state.

Constructor & Destructor Documentation

Rivet::VetoedFinalState::VetoedFinalState ( const VetoDetails & vetocodes ) [inline]

You can add a map of ID plus a pair containing $p_{Tmin}$ and $p_{Tmax}$ - these define the range of particles to be vetoed.

References Rivet::ProjectionApplier::addProjection(), Rivet::FinalState::FinalState(), and Rivet::Projection::setName().

Rivet::VetoedFinalState::VetoedFinalState	(	const FinalState &	fsp,
		const VetoDetails &	vetocodes
	)		`[inline]`

You can add a map of ID plus a pair containing $p_{Tmin}$ and $p_{Tmax}$ - these define the range of particles to be vetoed. This version also supplies a specifi FinalState to be used.

Member Function Documentation

VetoedFinalState& Rivet::VetoedFinalState::addCompositeMassVeto	(	const double &	mass,
		const double &	width,
		int	nProducts = `2`
	)		`[inline]`

Add a veto on composite masses within a given width. The composite mass is composed of nProducts decay products @ todo might we want to specify a range of pdg ids for the decay products?

VetoedFinalState& Rivet::VetoedFinalState::addDecayProductsVeto ( const long id ) [inline]

Veto the decay products of particle with pdg id

Todo:: Need HepMC to sort themselves out and keep vector bosons from the hard vtx in the event record before this will work reliably for all pdg ids

VetoedFinalState& Rivet::VetoedFinalState::addVetoDetail	(	const long	id,
		const double	ptmin,
		const double	ptmax
	)		`[inline]`

Add a particle ID and $ p_T $ range to veto. Particles with $ p_T $ IN the given range will be rejected.

Referenced by addVetoPairDetail().

VetoedFinalState& Rivet::VetoedFinalState::addVetoPairDetail	(	const long	id,
		const double	ptmin,
		const double	ptmax
	)		`[inline]`

Add a particle/antiparticle pair to veto in a given $ p_T $ range. Given a single ID, both the particle and its conjugate antiparticle will be rejected if their $ p_T $ is IN the given range.

References addVetoDetail().

VetoedFinalState& Rivet::VetoedFinalState::addVetoPairId ( const long id ) [inline]

Add a particle/antiparticle pair to veto. Given a single ID, both the particle and its corresponding antiparticle (for all $ p_T $ values) will be vetoed.

References addVetoId().

Referenced by vetoNeutrinos().

void Rivet::VetoedFinalState::project ( const Event & e ) [protected, virtual]

Apply the projection on the supplied event.

Todo:: Improve!

Reimplemented from Rivet::FinalState.
