Detailed Description

The DalitzGS class implements the Gounaris-Sakurai form of the propagator.

Definition at line 18 of file DalitzGS.h.

Constructor & Destructor Documentation

◆ DalitzGS()

Herwig::DalitzGS::DalitzGS ( )
inline

The default constructor.

Definition at line 27 of file DalitzGS.h.

Member Function Documentation

◆ BreitWigner()

virtual Complex Herwig::DalitzGS::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::DalitzGS::dataBaseOutput ( ofstream &  output)
virtual

Output the parameters.

Reimplemented from Herwig::DalitzResonance.

◆ Init()

static void Herwig::DalitzGS::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=()

DalitzGS & Herwig::DalitzGS::operator= ( const DalitzGS )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::DalitzGS::persistentInput ( PersistentIStream is,
int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
versionthe version number of the object when written.

◆ persistentOutput()

void Herwig::DalitzGS::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.
