Member Function Documentation

◆ clone()

virtual IBPtr Herwig::PiPiAnisovichKMatrix::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ doinit()

virtual void Herwig::PiPiAnisovichKMatrix::doinit ( )
protectedvirtual

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

Exceptions
InitExceptionif object could not be initialized properly.

Reimplemented from Herwig::KMatrix.

◆ fullclone()

virtual IBPtr Herwig::PiPiAnisovichKMatrix::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::PiPiAnisovichKMatrix::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.

◆ K()

virtual boost::numeric::ublas::matrix< double > Herwig::PiPiAnisovichKMatrix::K ( Energy2  s,
bool  multiplyByPoles = false 
) const
virtual

Compute the K-matrix for a given scale.

Parameters
sThe scale
Whetheror not to multiply by \(\prod_i(1-s/m^2_i\) to regularise the poles

Implements Herwig::KMatrix.

◆ operator=()

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

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

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

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.
