Detailed Description
template<typename Value>
class ThePEG::Helicity::LorentzSpinorBar< Value >
The LorentzSpinorBar class implements the storage of a barred LorentzSpinor.
The design is based on that of the LorentzSpinor class where the details of the implemented are discussed in more detail.

template<typename Value>
| LorentzSpinorBar ThePEG::Helicity::LorentzSpinorBar< Value >::conjugate | ( | ) | const |
Return the conjugated spinor .
This operation transforms u-spinors to v-spinors and vice-versa and is required when dealing with majorana particles.
