SUMMARY:Exploring the Unknown with Higgs Boson Pairs - Bill Balunas (Unive
 rsity of Cambridge)
DTSTART:20221122T110000Z

CONTACT:William Fawcett
DESCRIPTION:\nMuch progress has been made in understanding the Higgs boson
  in the ten years since its discovery. This has enabled its use as a new p
 robe for physics beyond the Standard Model\, which may be inaccessible thr
 ough any other means at present experiments. Higgs boson pair production e
 nables us to directly measure the shape of the Higgs potential via its sel
 f-interaction\, with far-reaching implications from our understanding of t
 he electroweak vacuum to baryogenesis in the early Universe. Experimental 
 constraints on this process at the LHC are sensitive both to direct produc
 tion of new particles that might decay to HH\, as well as indirect effects
  from fields that could interact with the Higgs in other ways\, including 
 at higher energy scales. This talk will present the theoretical background
  and latest results on Higgs boson pair production\, highlighting some of 
 the experimental challenges and modern approaches for overcoming them. Foc
 us will be given to recent ATLAS results\, and the bbbb final state in par
 ticular.
