One loop QCD corrections to gg → $$t\overline{t }H$$ at $$\mathcal{O}\left({\epsilon }^{2}\right)$$
Abstract We compute the one-loop corrections to gg → $$t\overline{t }H$$ up to order $$\mathcal{O}\left({\epsilon }^{2}\right)$$ in the dimensional-regularization parameter. We apply the projector method to compute polarized amplitudes, which generalize massless helicity amplitudes to the massive ca...
