Crunchy critical natural Higgs

I describe a new solution to the Higgs hierarchy problem based on a dynamical vacuum selection mechanism in a landscape which scans the Higgs mass. The Higgs potential only admits a stable minimum when its mass is less than a critical value, cosmologically crunching away patches with a heavier Higgs. This critical value is set by the instability scale where the Higgs quartic turns negative. I consider the phenomenology of two explicit models that address the hierarchy problem in this context.

The McDonald Institute seminar will be held in Stirling 501. A zoom link is also available and shared via email by the organizers. Please reach out to admin@mcdonaldinstitute.ca for access.
