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.

Famous quotes containing the word matter:
“No publisher should ever express an opinion on the value of what he publishes. That is a matter entirely for the literary critic to decide.... I can quite understand how any ordinary critic would be strongly prejudiced against a work that was accompanied by a premature and unnecessary panegyric from the publisher. A publisher is simply a useful middle-man. It is not for him to anticipate the verdict of criticism.”
—Oscar Wilde (1854–1900)
“It is a matter of perfect indifference where a thing originated; the only question is: “Is it true in and for itself?””
—Georg Wilhelm Friedrich Hegel (1770–1831)
“No matter which word it is, when I pronounce repeatedly, it ends up sounding utterly ridiculous and meaningless to me.”
—Franz Grillparzer (1791–1872)
