Relativistic particles

  1. Dec 24, 2008 #1
    Hey guys

    Just to clarify: theres nothing in current theories that forbids massless charged particles right? Its just we haven't found one yet. Do any of the group theory theories predict them or forbid them?(like the ones using the E8 group etc)

    If massless electrically charge particles existed, we already would have observed certain processes, but we haven't. See
