| + | <hidden TTP08-43 ${\cal O}(\alpha\alpha_s)$ corrections to the $\gamma t\bar{t}$ vertex at the top quark threshold > We compute the last missing piece of the | ||
| + | two-loop ${\cal O}(\alpha \alpha_s)$ corrections | ||
| + | to $\gamma t \bar{t}$ vertex at the $t \bar{t}$ threshold | ||
| + | due to the exchange of a $W$ boson and a gluon. This contribution | ||
| + | constitutes a building | ||
| + | block of the top quark threshold production cross section at electron | ||
| + | positron colliders. | ||
