Quarks transform in the fundamental representation under SU(3), gluons in the adjoint represention under SU(3), leaving the theory (QCD) invariant.
But how can I find out how quarks transform under SO(3)? I know how to decompose a Lorentz tensor under SO(3), like a four-vector or EM field strength vector. But what about fields in SU(3) representations? How can I see that the quarks are spinors and the glouns are vectors?
hope the question makes sense, thank you
