dc.descriptionWe compute the last missing piece of the two-loop ${\cal O}(αα_s)$ corrections to $γt \bar{t}$ 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.
