SUMMARY:Di-Higgs at the LHC: A Window on our Universe and BSM New Matter -

CONTACT:William Fawcett
DESCRIPTION:The discovery of the Higgs boson in 2012 provided the first di
 rect probe of the Higgs potential in experimental physics\, opening the do
 ors to an unprecedented era of precision Higgs measurements at the LHC (an
 d hopefully beyond!) A natural extension is to probe the global shape of t
 he Higgs potential\, which will provide direct insights into the stability
  of our universe and its early cosmology. At the LHC we are working to ach
 ieve just this through measuring the Higgs self-coupling in di-Higgs produ
 ction. This seminar will present the latest results from the ATLAS experim
 ent on searches for di-Higgs production\, the latest constraints on the Hi
 ggs self-coupling\, and smoking gun signatures for di-Higgs production fro
 m BSM matter. Prospects for future studies at the HL-LHC and potential cos
 mological consequences of a BSM Higgs self-coupling will also be presented
 .
