The quartic Higgs self-coupling is the final measurement in the Higgs potential needed to fully understand electroweak symmetry breaking. None of the present or future colliders are known to be able to determine this parameter. We study the chances of measuring the quartic self-coupling at hadron colliders in general and at the very large hadron collider in particular. We find the prospects challenging.

Probe Higgs potential via multi-Higgs boson final states at hadron colliders

I summarize some results related with the determination of the Higgs potential, including a hadron-level Monte Carlo study of the sensitivity of Higgs boson pair production via the WW∗WW∗ channel…

Measuring the Higgs sector

If we find a light Higgs boson at the LHC, there should be many observable channels which we can exploit to measure the relevant parameters in the Higgs sector. We use the SFitter framework to map…

Higgs self-coupling measurements at the LHC

Both the ATLAS and CMS collaborations have reported a Standard Model Higgs-like excess at around mh = 125 GeV. If an SM-like Higgs particle is discovered in this particular mass range, an important…

Higgs self-coupling measurements at a 100 TeV hadron collider

A bstractAn important physics goal of a possible next-generation high-energy hadron collider will be precision characterisation of the Higgs sector and electroweak symmetry breaking. A crucial part…

Shape of Higgs Potential at Future Colliders

Although the Higgs boson has been discovered, its self couplings are poorly constrained. It leaves the nature of the Higgs boson undetermined. Motivated by different Higgs potential scenarios other…

Multi-Higgs boson production in the standard model and beyond

We present a calculation of the loop-induced processes gg ! HH and gg ! HHH, and investigate the observability of multi-Higgs boson production at the CERN Large Hadron Collider (LHC) in the Standard…

NLO-QCD corrections to Higgs pair production in the MSSM

We take a step towards a complete NLO-QCD determination of the production of a pair of Higgs scalars in the MSSM. Exploiting a low-energy theorem that connects the Higgs-gluon interactions to the…
