A step closer in the quest for Higgs pair production at the LHC
The latest result in the search for Higgs pair production in ATLAS at the LHC, in the 4b final state, is now out:
with big contributions from the UCL ATLAS team, including the co-editor of the journal publication.
Higgs pair production (the production of two Higgs bosons in a single proton-proton collision at the LHC)
is a rare process that can shed light on the properties of the Higgs boson and particularly the Higgs field
potential (the famous "Mexican hat"). The Electroweak Phase Transition, one of the most dramatic and
defining moments in the evolution of our Universe, happened around 1 picosecond (one billionth of a
millisecond!) after the Big Bang. The shape of the Higgs field potential is intricately linked to that moment.
