The discussion centers on the production of Higgs bosons from top-antitop (t-tbar) pairs, particularly in the context of the LHC. It clarifies that while direct production of Higgs from t-tbar is possible, it is not the dominant process; rather, t-tbar production alongside a Higgs boson is more likely. The conversation also touches on the decay processes of top quarks, emphasizing that certain decays, such as top to Higgs plus charm, are forbidden at tree level in the standard model. Participants discuss the intricacies of Feynman diagrams related to these processes, including the correct representation of particle and antiparticle arrows. Ultimately, the consensus is that while Higgs production from t-tbar decays is theoretically conceivable, it remains an extremely rare occurrence.

Sure - you have have t -> H W* b. The branching fraction is about two in a billion.
