Non-resonant and electroweak NNLO correction to the $e^{+}{e}^{-}$ top anti-top threshold

Martin Beneke, Andreas Maier, Thomas Rauh +1

We determine the NNLO electroweak correction to the $e^{+}{e}^{-}\to b\bar{b}{W}^{+}{W}^{-}X$ production cross section near the top-pair production threshold. The calculation includes non-reso…
