hh+Jet production at 100 TeV.

Banerjee, Shankha and Englert, Christoph and Mangano, Michelangelo L. and Selvaggi, Michele and Spannowsky, Michael (2018) 'hh+Jet production at 100 TeV.', European physical journal C., 78 (4). p. 322.


Higgs pair production is a crucial phenomenological process in deciphering the nature of the TeV scale and the mechanism underlying electroweak symmetry breaking. At the Large Hadron Collider, this process is statistically limited. Pushing the energy frontier beyond the LHC’s reach will create new opportunities to exploit the rich phenomenology at higher centre-of-mass energies and luminosities. In this work, we perform a comparative analysis of the hh+jet channel at a future 100 TeV hadron collider. We focus on the hh→bb¯bb¯ and hh→bb¯τ+τ− channels and employ a range of analysis techniques to estimate the sensitivity potential that can be gained by including this jet-associated Higgs pair production to the list of sensitive collider processes in such an environment. In particular, we observe that hh→bb¯τ+τ− in the boosted regime exhibits a large sensitivity to the Higgs boson self-coupling and the Higgs self-coupling could be constrained at the 8% level in this channel alone.
