报告摘要:
Since its discovery at the LHC in 2012, a number of studies have
shown that the Higgs boson has properties very similar to those predicted by
the Standard Model. However, virtually no experimental information exists about
the Higgs self-coupling, which has important consequences for understanding the
electroweak phase transition and physics beyond the Standard Model. In this
talk, I will discuss how future proton colliders could measure the Higgs
self-coupling and give us insight into early universe cosmology. I will start
with a review of Higgs physics and how the self-coupling is related to
electroweak symmetry breaking and hence the early universe phase transition. I
will then describe how the self-coupling can be measured via Higgs pair
production at a hadron collider and summarize the current limits, focusing on
the hh-bb?? decay channel.
Finally, I will review previous studies on the capabilities of a 100 TeV
collider such as FCC-hh at CERN or SPPC in China and preview our results on the
capabilities of a 27 TeV collider such as HE-LHC.
