I don't know that much about GUT's, but am interested in them. My question is can they be used to explain the Yukawa coupling constants like [tex]G_e[/tex] which appear in terms like:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

L_{\phi e} = - G_e \left( {\begin{array}{*{20}c}

{\bar \upsilon _e } \\

{\bar e} \\

\end{array} } \right)_L \left( {\begin{array}{*{20}c}

{\phi ^ + } \\

{\phi ^0 } \\

\end{array} } \right)e_R

[/tex]

If so, how does this work.
