Contribution
It introduces five scenarios demonstrating that precision Higgs coupling measurements can reveal multi-TeV scale new physics beyond direct detection.
Findings
Precision measurements can detect deviations caused by multi-TeV particles.
Such measurements extend the reach beyond HL-LHC direct searches.
Multiple scenarios show significant coupling deviations from heavy new particles.
Abstract
To understand the possibility for precision Higgs boson coupling measurements to access effects of very heavy new particles, I present five scenarios in which significant deviations in Higgs boson couplings are produced by new particles with multi-TeV masses. These scenarios indicate that such precision measurements provide opportunities to reach well beyond the capabilities of direct particle searches at the HL-LHC.
