The production of a Higgs boson in association with a pair of t-tbar quarks will play a very important role at both hadron and lepton colliders. We review the status of theoretical predictions and their relevance to Higgs boson studies,…

The generation of single top production in the $Wt$ channel at NLO gives rise to doubly-resonant diagrams that overlap with $t \bar t$, and similarly for associated production with a $Z$ or Higgs boson. Several methods exist to remove this…
