Abstract
At moderate values of tanβ , a supersymmetric charged Higgs boson H ± is difficult to find due its small cross section and large backgrounds. Using realistic boosted tagging rates, we present preliminary predictions for the reach for TeV-scale charged Higgs bosons at 14 TeV and 100 TeV colliders in top-Higgs associated production. We conclude that moderate values of tanβ will be possible to probe at a 100 TeV collider.

After the discovery of a 126 GeV Higgs-like boson at the Large Hadron Collider at CERN, the emphasis has shifted to whether this is the Higgs boson of the Standard Model, or if it is merely one degree of freedom in a larger model like supersymmetry (SUSY)
Excitement was generated by a claim [1] that the “wedge region” in tan β could be explored up to 2 TeV in H± mass at a 14 TeV LHC through the channel tbH± → tb(tb)
At ISMD this year we presented the results of an analysis to find the reach for TeV-scale charged Higgs bosons at the LHC and at a future 100 TeV collider
Summary
After the discovery of a 126 GeV Higgs-like boson at the Large Hadron Collider at CERN, the emphasis has shifted to whether this is the Higgs boson of the Standard Model, or if it is merely one degree of freedom in a larger model like supersymmetry (SUSY). Experiment already constrains SUSY models to be in the “alignment limit,” where the masses of these new Higgs states are nearly degenerate. The H± bosons couple almost exclusively to third generation quarks. Given the strength of the tbH± Yukawa coupling, the dominant production mode for charged Higgs bosons at the LHC is in association with a top quark, where the Higgs decays to a boosted top jet and boosted bottom jet final state. Excitement was generated by a claim [1] that the “wedge region” in tan β (tan β ∼ 6 where the h0 shares equal coupling to top and bottom at leading order) could be explored up to 2 TeV in H± mass at a 14 TeV LHC through the channel tbH± → tb(tb). We utilize our new boosted bottom jet tag [3, 4] to examine whether the ∼ 2 TeV limit can be reached in the SUSY wedge region at the LHC or at a future 100 TeV pp collider
