Public Member Functions  
SpinCorrelationTensor (double diag, const Lorentz5Momentum &p, Energy2 sc)  
The standard constructor, giving diagonal part, and vector for offdiagonal components and the scale.  
double  diagonal () const 
Return the diagonal part.  
const Lorentz5Momentum &  momentum () const 
Return the offdiagonal vector part.  
Energy2  scale () const 
Return the scale.  
Complex  matrixElement (const LorentzVector< Complex > &left, const LorentzVector< Complex > &right) const 
Return a matrix element of the diagonal part, by contracting with the given polarization vectors.  
Private Attributes  
double  theDiagonal 
The diagonal part.  
Lorentz5Momentum  theMomentum 
The vector to define to offdiagonal part.  
Energy2  theScale
