Electroweak corrections to $t\bar{t}$ production at hadron colliders
  We report on our recent work on electroweak corrections to $t\bar{t}$ production at hadron colliders. Specifically, we discuss the weak-interaction contributions to the top quark transverse momentum and $t \bar{t}$ invariant mass distributions and an induced parity-violating top-spin asymmetry.
