Member Function Documentation

◆ clone()

virtual IBPtr Herwig::ResonantProcessConstructor::clone ( ) const

protectedvirtual

Make a simple clone of this object.

Returns: a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ constructDiagrams()

void Herwig::ResonantProcessConstructor::constructDiagrams ( )

virtual

The main function to create the resonant diagrams.

Implements Herwig::HardProcessConstructor.

◆ doinit()

virtual void Herwig::ResonantProcessConstructor::doinit ( )

protectedvirtual

Initialize this object after the setup phase before saving an EventGenerator to disk.

Exceptions

InitException if object could not be initialized properly.

Reimplemented from Herwig::HardProcessConstructor.

◆ fullclone()

virtual IBPtr Herwig::ResonantProcessConstructor::fullclone ( ) const

protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns: a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

◆ Init()

static void Herwig::ResonantProcessConstructor::Init ( )

static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ operator=()

ResonantProcessConstructor & Herwig::ResonantProcessConstructor::operator= ( const ResonantProcessConstructor & )

privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::ResonantProcessConstructor::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.

Parameters

is	the persistent input stream read from.
version	the version number of the object when written.

◆ persistentOutput()

void Herwig::ResonantProcessConstructor::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.

◆ search()

tPDSet Herwig::ResonantProcessConstructor::search	(	VertexBasePtr	vertex,
		long	part1,
		direction	d1,
		long	part2,
		direction	d2,
		direction	d3 = `outgoing`
	)

private

Given a vertex and 2 particle id's find the possible states that can be the 3rd external particle.

Parameters

vertex	Pointer to the vertex
part1	id of first particle
d1	direction of particle one
part2	id of other particle
d2	direction of particle two
d3	required direction of 3rd state (default = outgoing)
