- TL;DR Summary
- D(1,1) means one quark and one antiquark, which corresponds perfectly to mesons. But how can it explain baryons?

The question may be ambiguous but it's really simple. One says that the baryon octet is the D(1,1) representation of SU(3), but then uses the same one for mesons. D(1,1) means one quark and one antiquark, which corresponds perfectly to mesons. But how can it explain baryons?
