Description
The discovery of the Higgs boson by the LHC in 2012, and especially
the determination of its mass around 125 GeV, together with the absence
of any trace of new physics, make it conceivable that we live in a metastable
electroweak vacuum. This vacuum turns out to be extremely long-lived as that
particular mass value means we live quite close to the stability boundary. I will
describe the state-of-the-art calculation that leads to this intriguing conclusion
and elaborate on possible implications as well as a simple cure of this instability
of the Higgs potential.
