Public Member Functions
int	compare (const Projection &p) const
	Compare to another SmearedMET.

void	project (const Event &e)

	Clone on the heap.

Transverse momentum functions
Note This may be what you want, even if the paper calls it "missing Et"! Todo: Move into a common base class for MissingMomentum and SmearedMET – MomentumBalance, METFinder?

	Convenience vector MPT function.

const Vector3	vectorMPT () const

double	missingPt () const
	The vector-summed missing transverse momentum in the event.

Transverse energy functions
Warning Despite the common names "MET" and "SET", what's often meant is the pT functions above! Todo: Move into a common base class for MissingMomentum and SmearedMET – MomentumBalance, METFinder?

const Vector3	vectorMissingEt () const
	Convenience vector MET function.

Constructor & Destructor Documentation

◆ SmearedMET()

template<typename V2VFN >

Rivet::SmearedMET::SmearedMET	(	const MissingMomentum &	mm,
		const V2VFN &	metSmearFn
	)

inline

Constructor from a MissingMomentum projection and a smearing function.

Smearing function maps a 3-vector MET and scalar SET to a new MET 3-vector: f(V3, double) -> V3

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

Member Function Documentation

◆ vectorEt()

const Vector3& Rivet::SmearedMET::vectorEt ( ) const

inline

The vector-summed visible transverse energy in the event, as a 3-vector with z=0

Note: Reverse this vector with operator- to get the missing ET vector.

Referenced by missingEt(), vectorMissingEt(), and vectorPt().

◆ vectorPt()

const Vector3& Rivet::SmearedMET::vectorPt ( ) const

inline

The vector-summed visible transverse momentum in the event, as a 3-vector with z=0

Note: Reverse this vector with operator- to get the missing pT vector.

Todo:: Currently equivalent to vectorEt
