Hi,
When one quantizes EM the resulting gauge boson, the photon, ends up being its own antiparticle. From what I read of gluons, they have anti particles. I can follow how anti particles come about quantizing a complex-valued field like that for electrons. For the spin 1/2 case non-interacting fields are sums of particle - anti particle annihilation operators. How does this end up working for the gluon case which are 8 spin 1 real-valued fields?
