Here, $C_{V/A}^{\rm ax}$ are Born level Wilson coefficients of operators describing top pair production in a P-wave (originating from pure Z exchange), ${\cal V}_r^{(s)}$ is the color singlet coefficient of the potential $({\mathbf p}^2+{\mathbf p}^{\prime\,2})/(2m_t({\mathbf p}-{\mathbf p}^\prime)^2)$ [@HoangStewartultra] and $c_2$ the coefficient of the ${\mathbf p}^2$-suppressed S-wave production current [@hmst1]. The explicit formulae read $$\begin{aligned}
