Adjoint-Higgs breaking of SU(3) to SU(2) and U(1)
= Adjoint-Higgs breaking of SU(3) to SU(2) and U(1)
{title2=$SU(3)\to S(U(2)\times U(1))$}
For an adjoint <vacuum expectation value> proportional to $\operatorname{diag}(1,1,-2)$, the <centralizer> is $(SU(2)\times U(1))/\mathbb Z_2$. Four <gauge bosons> remain massless and four acquire a common mass. This differs from <Fundamental-Higgs breaking of SU(3) to SU(2)>.
