Detailed Description

Author

Peter Richardson

The HardVertex class is designed to implement the vertex for a hard interaction for the Herwig spin correlation algorithm. It inherits from the HelicityVertex class of ThePEG and implements the methods to calculate the \(\rho\) and \(D\) matrices.

The ProductionMatrixElement class is used to store the matrix element and this class performs the calculations of the matrices.
