{title2=$SU(3)_c\times SU(2)_L\times U(1)_Y$}
In the <MSSM>, each <fermion generation> has <chiral superfields> $Q:(3,2,1/6)$, $U^c:(\bar3,1,-2/3)$, $D^c:(\bar3,1,1/3)$, $L:(1,2,-1/2)$, and $E^c:(1,1,1)$. This uses <hypercharge> normalized by $Q_{\rm electric}=T^3+Y$ and only left-handed <Weyl spinors>. Two <Higgs chiral doublets> have charges $\pm1/2$. The three <vector superfields> transform as $(8,1,0)$, $(1,3,0)$ and $(1,1,0)$, supplying the <gauge bosons> and <gauginos>.
