= Unitary scalar multiplet current
{title2=$j_T^\mu=i[(\partial^\mu\Phi^\dagger)T\Phi-\Phi^\dagger T\partial^\mu\Phi]$}
For a <complex scalar field> multiplet with canonical kinetic term and <scalar potential> invariant under $\Phi\mapsto e^{i\varepsilon T}\Phi$, a constant <Hermitian matrix> $T$ gives the displayed <Noether current>. Vary the field and its conjugate independently in the <Noether current for a first-derivative scalar field>. A common alternative convention reverses both the parameter and current sign. Its divergence vanishes <on shell>.
