Description
We investigate Higgs boson pair production at hadron colliders for Higgs boson masses mH ≤140 GeV and rare decay of one of the two Higgs bosons. While in the Standard Model the number of events is quite low at the LHC, a first, albeit not very precise, measurement of the Higgs self-coupling is possible in the gg→HH→ b anti bγγ channel. A luminosity-upgraded LHC could improve this measurement considerably. A 200 TeV VLHC could make a measurement of the Higgs self-coupling competitive with a next-generation linear collider. In the MSSM we find a significant region with observable Higgs pair production in the small tan β regime, where resonant production of two light Higgs bosons might be the only hint at the LHC of an MSSM Higgs sector.
