Detailed Description

Class to store general Event setup, i.e. Phase space and weights.

Constructor & Destructor Documentation

◆ EventData() [1/3]

HEJ::Event::EventData::EventData ( )

default

Default Constructor.

◆ EventData() [2/3]

HEJ::Event::EventData::EventData ( LHEF::HEPEUP const & hepeup )

Constructor from LesHouches event information.

◆ EventData() [3/3]

HEJ::Event::EventData::EventData	(	std::array< Particle, 2 >	incoming,
		std::vector< Particle >	outgoing,
		std::unordered_map< std::size_t, std::vector< Particle > >	decays,
		Parameters< EventParameters >	parameters
	)

inline

Constructor with all values given.

Member Function Documentation

◆ cluster()

Event HEJ::Event::EventData::cluster	(	fastjet::JetDefinition const &	jet_def,
		double	min_jet_pt
	)

Generate an Event from the stored EventData.

Do jet clustering and classification. Use this to generate an Event.

Note: Calling this function destroys EventData

Parameters

jet_def	Jet definition
min_jet_pt	minimal \(p_T\) for each jet

Returns: Full clustered and classified event.

◆ operator()()

Event HEJ::Event::EventData::operator()	(	fastjet::JetDefinition const &	jet_def,
		double const	min_jet_pt
	)

inline

Alias for cluster()

◆ reconstruct_intermediate()

void HEJ::Event::EventData::reconstruct_intermediate ( )

Reconstruct intermediate particles from final-state leptons.

Final-state leptons are created from virtual photons, W, or Z bosons. This function tries to reconstruct such intermediate bosons if they are not part of the event record.

◆ sort()

void HEJ::Event::EventData::sort ( )

Sort particles in rapidity.

Member Data Documentation

◆ decays

std::unordered_map<std::size_t, std::vector<Particle> > HEJ::Event::EventData::decays

Particle decays in the format {outgoing index, decay products}.

◆ incoming

std::array<Particle, 2> HEJ::Event::EventData::incoming

Incoming particles.

◆ outgoing

std::vector<Particle> HEJ::Event::EventData::outgoing

Outcoing particles.

◆ parameters

Parameters<EventParameters> HEJ::Event::EventData::parameters

Parameters, e.g. scale or inital weight.
