In order to obtain the non-relativistic limit of $T^{ijk}(\lambda )$, denoted by $t^{ijk}(\lambda )$, we use

$$\begin{aligned}
&&\frac 1{2E_d}-\frac 1{2E_x}\sim \frac{{\mbox{\boldmath $p $}}^2}{m^3}, \\
&&\frac 1{2E_d\left( p_d^0+E_d\right) }+\frac 1{2E_x\left( p_x^0+E_x\right) }%
\sim \frac 1{2m^2},\end{aligned}$$
