Englert, Christoph and Krauss, Frank and Spannowsky, Michael and Thompson, Jennifer (2015) 'Di-Higgs phenomenology in t¯thh : the forgotten channel.', Physics letters B., 743 . pp. 93-97.
Searches for multi-Higgs final states allow to constrain parameters of the SM (or extensions thereof) that directly relate to the mechanism of electroweak symmetry breaking. Multi-Higgs production cross sections, however, are small and the phenomenologically accessible final states are challenging to isolate in the busy multi-jet hadron collider environment of the LHC run 2 and HL-LHC. This makes the necessity to extend the list of potentially observable production mechanisms obvious. Most of the phenomenological analyses in the past have focused on gg→hh +jets; in this paper we study pp →t¯thhat the HL-LHC and find that this channel for h →b¯ band semi-leptonic and hadronic top decays has the potential to provide an additional handle to constrain the Higgs trilinear coupling in a global fit at the end of the high luminosity phase.
