Cosmological Relaxation of the Electroweak Scale

Explore a groundbreaking lecture on a novel approach to solving the electroweak hierarchy problem in particle physics. Delve into a class of solutions that eschews both weak-scale dynamics and anthropic reasoning. Discover how the early Universe's dynamical evolution can naturally lead to a Higgs boson mass significantly lower than the cutoff scale. Examine the simplest model proposed, which builds upon the Standard Model by incorporating a QCD axion and an inflation sector. Gain insights into this innovative cosmological mechanism and its potential implications for our understanding of fundamental physics.
