StdHep::Particle

StdHep::Particle contains the volatile particle information: Particle ID, status code, mother, second mother, an index to the first daughter, an index to the last daughter, color, momentum CLHEP Lorentz vector, generated mass, helicity, creation vertex CLHEP Lorentz vector, and decay vertex CLHEP Lorentz vector. The mother, second mother, and indices to first and last daughter are deliberately designed to be compatible with the HEPEVT common block. StdHep::Particle also contains a method to access the appropriate StdHep::ParticleData.
