Detailed Description
template<typename Value>
class ThePEG::Lorentz5Vector< Value >
The Lorentz5Vector inherits from the LorentzVector class.
It is templated on the type of the member variables. The Lorentz5Vector class is a LorentzVector with an extra member for the invariant length/mass of the vector. Note that an object of the Lorentz5Vector class may be internally inconsistent in that the invariant length/mass of the LorentzVector class need not be the same as the member variable representing the invariant length/mass. The degree of inconsistency can be accessed with the massError(), energyError() and rhoError() methods and an object can be made consistent using the rescaleMass(), rescaleEnergy() or rescaleRho() methods.
