Current measurements of the Higgs boson mass and top Yukawa coupling suggest that the effective Higgs potential develops an instability below the Planck scale. If the energy scale of inflation in the early Universe is as high as the GUT scale, inflationary quantum fluctuations of the Higgs field can easily destabilize the standard electroweak vacuum. This instability produces dangerous AdS domains which should have swallowed the whole Universe.

Notice: In the seminar, there will be a mini lecture by Prof. Ryuichiro Kitano (KEK theory center) on the renormalization of the Higgs potential prior to Kohri-san's talk.
