| Sep 5, 2019 at 15:34 | comment | added | MadMax | @mithusengupta123, as I mentioned in the answer, the discussion is in the context of BSM (with gauge group $U(3)*SU(2)*U(1)$). We don't have a 9th "gluon" in SM, right? | |
| Sep 5, 2019 at 15:31 | comment | added | Solidification | I didn't understand the answer. The strong interaction is described by color SU(3), and the decomposition $3\times 3^*=8+1$ means we have an octet that transforms like an irreducible representation of SU(3) and another like a singlet of SU(3). I don't know where you get a U(3) from. I think you are mixing up flavor SU(3) with color SU(3). | |
