class ROOT::Math::LorentzVector<ROOT::Math::PxPyPzE4D<Double32_t> >


        Class describing a generic LorentzVector in the 4D space-time,
        using the specified coordinate system for the spatial vector part.
        The metric used for the LorentzVector is (-,-,-,+).
        In the case of LorentzVector we don't distinguish the concepts
        of points and displacement vectors as in the 3D case,
        since the main use case for 4D Vectors is to describe the kinematics of
        relativistic particles. A LorentzVector behaves like a
        DisplacementVector in 4D.  The Minkowski components could be viewed as
        v and t, or for kinematic 4-vectors, as p and E.
