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 | |
