With a small ${\\cal{O}}(30)$ fb Standard Model production cross section, and a large $t\\bar t$ background, this measurement has been considered challenging, even at a luminosity-upgraded LHC. We demonstrate that by using simple kinematic bounding variables, of the sort already employed in existing LHC searches, the dominant $t\\bar t$ background can be largely eliminated. Simulations of the signal and the dominant background demonstrate the prospect for measurement of the di-Higgs production cro","authors_text":"Alan J. Barr, Christoph Englert, Matthew J.
