Public Member Functions

 SpinCorrelationTensor (double diag, const Lorentz5Momentum &p, Energy2 sc)
 The standard constructor, giving diagonal part, and vector for off-diagonal components and the scale.
 
double diagonal () const
 Return the diagonal part.
 
const Lorentz5Momentum & momentum () const
 Return the off-diagonal 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
