Bino
= Bino
{title2=$\widetilde B$}
The <bino> is the spin-one-half <gaugino> of the <hypercharge> $U(1)_Y$ <gauge group>. Its adjoint representation is the singlet $(\mathbf1,\mathbf1,0)$, so it has no hypercharge of its own. After <electroweak symmetry breaking>, it can mix with the neutral <wino> and <higgsinos> into <neutralinos>.
