SU(2) gauge theory with an adjoint Higgs field
= SU(2) gauge theory with an adjoint Higgs field
{c}
{title2=$SU(2)\to U(1)$}
A real <scalar field> in the <Adjoint representation> can have a nonzero <vacuum expectation value>, leaving one massless and two massive <gauge bosons>. This breaking differs from <electroweak symmetry breaking> by a complex <Higgs doublet>.
