Precarious Naturalness

This lecture by the instructor explores the concept of precarious naturalness, addressing the hierarchy problem and the cosmological constant issue. It introduces post-naturalness paradigms and proposes a new mechanism for post-naturalness. The discussion covers living at the top of the potential, solving hierarchy problems, and the selection mechanism based on anthropic and environmental factors. The presentation delves into quantitative aspects, anthropic cosmological constants, and the implications for the Universe's stability. It also touches on the role of loops, inflationary dynamics, and the precarious nature of the Universe. The conclusions highlight the resolution of hierarchy and cosmological constant problems, the precarious state of the Universe, and the potential for new physics discoveries.
