Does massless charge exist?

We do have numerous particles with zero electric charge and nonzero mass, but do we have particles with zero mass and nonzero electric charge?

I don't think something like that exists. To have a charge would mean loss or gain of electrons, and electrons do have nonzero mass. So, nonzero charge would simply imply nonzero mass, wouldn't it?

@OP: The only massless particle is the photon (that we know of). Something with zero mass and an electric charge would be easily detectable and easily created. If it did exist, I believe it would mean QED would be all sorts of screwed up, and we know QED is amazingly accurate.

Does massless charge exist?
I need some reference not views of an individual what he/she thinks. Electron is a lepton, has a charge of its own. Quarks do have charges( both ve and +ve) how can u relate them with gain or loss of electrons?? Charge is an attribute or intrinsic properties, u cannot relate it specially with electrons only!

The EM field carries massenergy, so since a particle with an electric charge acts as a source of the EM field, it must have mass.

Please correct me if I'm wrong, but since Einstein's formula suggests that E=mc^2, if a particle other than the photon where to have 0 mass, 0 energy would be required to create it. That is why it would be extremely easy to make such a particle.

That's kind of scary to think of. I am instantaly alarmed. I honestly think something like this cannot exisit. Anything with no mass cannot exsist.

Light exists, does it not? It has no mass!

http://en.wikipedia.org/wiki/Koide_formula
The Koide formula is an unexplained relation discovered by Yoshio Koide in 1981. It relates the masses of the three charged leptons so well that it predicted the mass of the tau. The mystery is in the physical value. The masses of the electron, muon, and tau are measured respectively as me = 0.510998910(13) MeV/c2, mμ = 105.658367(4) MeV/c2, and mτ = 1,776.84(17) MeV/c2, where the digits in parentheses are the uncertainties in the last figures.[1] This gives Q = 0.666659(10).[2] Not only is this result odd in that three apparently random numbers should give a simple fraction, but also that Q is exactly halfway between the two extremes of 1⁄3 and 1.
