Under $SU(3)_c\times SU(2)_L\times U(1)_Y$, one generation consists of
$$
Q_L:(\mathbf3,\mathbf2)_{1/6},\quad
u_R:(\mathbf3,\mathbf1)_{2/3},\quad
d_R:(\mathbf3,\mathbf1)_{-1/3},
$$
$$
L_L:(\mathbf1,\mathbf2)_{-1/2},\quad
e_R:(\mathbf1,\mathbf1)_{-1},\quad
\nu_R:(\mathbf1,\mathbf1)_0.
$$
These are the fundamental fermions of the <Standard Model> augmented by a right-handed neutrino.
