Member Function Documentation

◆ BreitWigner()

virtual Complex Herwig::PiPiI2::BreitWigner	(	const Energy &	mAB,
		const Energy &	mA,
		const Energy &	mB
	)		const

virtual

Return the Breit-Wigner times the form factor.

Reimplemented from Herwig::DalitzResonance.

◆ dataBaseOutput()

virtual void Herwig::PiPiI2::dataBaseOutput ( ofstream & output )

virtual

Output the parameters.

Reimplemented from Herwig::DalitzResonance.

◆ Init()

static void Herwig::PiPiI2::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=()

PiPiI2 & Herwig::PiPiI2::operator= ( const PiPiI2 & )

privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

		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::PiPiI2::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.
