Higgs@UCL

The Higgs boson was discovered by the ATLAS and CMS collaborations in 2012. UCL pioneered the search for the decay into a pair of b-quarks and continues to demonstrate it’s potential at the energy frontier. We played a leading role in the first observation of this channel in 2019 and, subsequently, in the precise measurement of this branching ratio.

UCL also pioneered the search for resonant and non-resonant Higgs boson pair production in the HH->bbbb (4b) final state, recognizing and demonstrating early that this is the most powerful channel in the search for heavy resonances decaying to a pair of Higgs bosons (X->HH), as well as one of the most sensitive channels in the search for non-resonant di-Higgs production and the study of the Higgs self-coupling, which will provide insights into the shape of the Higgs potential and the role of the Higgs field in cosmology and the early moments of the Universe.
