DESCRIPTION:New physics at the TeV scale or lower may destabilise the elec
 troweak vacuum. How low could the vacuum instability scale be? This fundam
 ental question may be tied to a deeper understanding of the Higgs potentia
 l and its associated hierarchy problem. The scale of vacuum instability ca
 n be viewed as an upper bound on the Higgs mass---the so-called vacuum met
 astability bound---and criticality of the Higgs potential through some und
 erlying mechanism then places our universe at this metastable point. In th
 is talk\, I summarise recent work developing this eminently testable hypot
 hesis. If the vacuum metastability bound plays a role in determining the p
 roperties of the Higgs boson\, the new physics responsible will likely be 
 discovered or excluded in the entire natural region of parameter space at 
 future facilities. This makes it a tantalising and attractive target for f
 uture colliders.\n\nhttps://agenda.infn.it/event/46409/
