Constructor Detail

BasicParticle

public BasicParticle(Hep3Vector origin,
                     HepLorentzVector p,
                     ParticleType ptype,
                     int status,
                     double time)

Create a new BasicParticle

Parameters:

origin - The origin of this particle

p - The momentum and energy of this particle

ptype - The type of this particle

status - The status of this particle

time - The production time of this particle

Method Detail
