Goldstino null vector with F-term and D-term breaking ($\mathcal{M}(F,D/\sqrt{2}{)}^T=0$)

For canonical global four-dimensional N=1 supersymmetry, define $F^i=\overline{W_i}$, $H_{ij}=W_{ij}$ and $G_{ia}=g^a{\bar{\varphi }}_j(T^a{)}^j{}_i$ at a stationary vacuum. Gauge invariance of the superpotential gives $G^{T}F=0$, while stationarity of $V={\sum }_i|W_i{|}^2+\frac{1}{2}{\sum }_a(D^a{)}^2$ gives $HF-GD=0$. Therefore the canonically normalized fermion mass matrix, after a harmless gaugino phase choice, obeysIf supersymmetry is broken, this vector is nonzero and specifies a massless Goldstino. The matrix with off-diagonal blocks $-G$ instead acts on $(F,D)$; it is related to the canonical matrix by a change of normalization, not by equality of canonical entries. Additional zero modes can coexist with the Goldstino.
