Discovering Higgs boson pair production through rare final states at a 100 TeV collider

We consider the process of Higgs boson pair production at a future proton collider with a center-of-mass energy of 100 TeV, focusing on rare final states that include a bottom-antibottom quark pair and multiple isolated leptons: hh --> (b (b) over bar) + nl + X, n = {2, 4}, X = {(E) over bar (T), gamma, -}. We construct experimental search strategies for observing the process through these channels and make suggestions on the desired requirements for the detector design of the future collider.
