Description
The t-tbar-Higgs-Higgs (tthh) channel was once called the forgotten channel, as the small cross section made it widely believed that this channel could not compete with ttH or Double Higgs in terms of probing Standard Model couplings and the physics beyond. I'll review a set of recent works that show how this channel is not only complementary, but also competitive, specially in terms of constraining effective operators that only appear here at tree level. I'll go further and show some interesting beyond SM models that generate those operators, such as Composite Higgs Models, and their particular signal in the ttHH channel.
