Are Massless Charged Particles Forbidden by Current Group Theory Theories?

Hey guys

Just to clarify: there's 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)

Thanks

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

Thread 'Euclidean geometry and gravity'

I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say near a black hole, and I draw a triangle on this paper and 'measure' the angles of the triangle, will they add to 180 degrees? How about if I'm looking at this paper outside of the (reasonable)...

Thread 'Jackson: justification of the Poynting vector by GR'

The Poynting vector is a definition, that is supposed to represent the energy flow at each point. Unfortunately, the only observable effect caused by the Poynting vector is through the energy variation in a volume subject to an energy flux through its surface, that is, the Poynting theorem. As a curl could be added to the Poynting vector without changing the Poynting theorem, it can not be decided by EM only that this should be the actual flow of energy at each point. Feynman, commenting...
