SUMMARY
The forum discussion centers on the processes for Higgs boson production from top-antitop (t-tbar) pairs, particularly in the context of the Large Hadron Collider (LHC). It is established that while direct production of Higgs from t-tbar is possible, the dominant process involves the formation of t-tbar pairs, which can lead to Higgs production through mechanisms such as t -> H + W* + b, albeit with a very low branching fraction of approximately 2 in a billion. The discussion also clarifies that decays like top -> H + charm are forbidden at tree level in the Standard Model, and emphasizes the importance of understanding Feynman diagrams in depicting these interactions accurately.
