NLO QCD Predictions for off-shell $t\bar{t}$ and $t\bar{t}H$ Production and Decay at a Linear Collider

Bijan Chokoufé Nejad, Wolfgang Kilian, Jonas M. Lindert +3

We present predictions for $t\bar{t}$ and $t\bar{t}H$ production and decay at future lepton colliders including non-resonant and interference contributions up to next-to-leading o…
