Abstract

We present a feasibility study of observing HH→ b bγγ at the future hadron colliders with √(s)=14, 33, and 100 TeV. The measured cross section then can be used to constrain the Higgs self-coupling directly in the standard model. Any deviation could be a sign of new physics. The signal and background events are estimated using Delphes 3.0.10 fast Monte Carlo simulation based on the ATLAS detector capabilities. With 3 ab^-1 data, it would be possible to measure the Higgs self-coupling with a 50%, 20%, and 8% statistical accuracy by observing HH→ b bγγ at √(s)=14, 33, and 100 TeV colliders, respectively.
