Member Function Documentation

◆ getDMatrix()

RhoDMatrix Herwig::DipoleShowerVertex::getDMatrix ( int  ) const
virtual

Method to calculate the $D$ matrix for the decaying particle / the incoming to the vertex, in the frame of the vertex.

The argument is a dummy argument.

Implements ThePEG::HelicityVertex.

◆ getRhoMatrix()

RhoDMatrix Herwig::DipoleShowerVertex::getRhoMatrix ( int  iprod,
bool   
) const
virtual

Method to calculate the $\rho$ matrix for one of the decay products in the frame of this splitting vertex.

Parameters
iprodThe splitting product to compute the $\rho$ matrix for.

Implements ThePEG::HelicityVertex.

◆ Init()

static void Herwig::DipoleShowerVertex::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=()

DipoleShowerVertex& Herwig::DipoleShowerVertex::operator= ( const DipoleShowerVertex )
private

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
