Detailed Description

Author
Peter Richardson

The DecayVertex class is designed to implement the vertex for a decay for use with the spin correlation algorithm. 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.
