Analytic two-loop corrections to top-quark pair production at hadron colliders
We present the complete two-loop QCD amplitudes for the production of a top-quark pair in the quark--antiquark annihilation and gluon-fusion channels in analytic form up to order $\mathcal{O}(\varepsilon^2)$. Our analysis maintains full dependence on the top-quark mass and on the number of colours. The amplitudes are e...
