Matter
The matter representations come in three copies (generations) of the 16 representation. The Yukawa coupling is 10H 16f 16f. This includes a right-handed neutrino. We can either include three copies of singlet representations φ and a Yukawa coupling (see double seesaw mechanism) or add the Yukawa interaction or add the nonrenormalizable coupling . See seesaw mechanism.
