Detailed Description

Author
Peter Richardson

The ShowerVertex class is designed to implement the vertex for a branching in the shower for use with the spin correlation alogorithm. It inherits from HelicityVertex class of ThePEG and implements the methods to calculate the $\rho$ and $D$ matrices.

It uses the DecayMatrixElement class to store the matrix element and it is this class which performs the calculations of the matrices.

Member Function Documentation

◆ getDMatrix()

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

Method to calculate the $D$ matrix for the decaying particle.

It this case the argument is a dummy.

Implements ThePEG::HelicityVertex.

◆ getRhoMatrix()

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

Method to calculate the $\rho$ matrix for one of the decay products.

Parameters
iprodThe product we are calculating the $\rho$ matrix for.

Implements ThePEG::HelicityVertex.

◆ Init()

static void Herwig::ShowerVertex::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.

◆ ME()

const DecayMEPtr Herwig::ShowerVertex::ME ( ) const
inline

Access to the matrix element.

Get the matrix element

Definition at line 59 of file ShowerVertex.h.

◆ operator=()

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

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
